|---|---|---|---|
| GO:0006614 | SRP-dependent cotranslational protein targeting to membrane | The targeting of proteins to a membrane that occurs during translation and is dependent upon two key components, the signal-recognition particle (SRP) and the SRP receptor. SRP is a cytosolic particle that transiently binds to the endoplasmic reticulum (ER) signal sequence in a nascent protein, to the large ribosomal unit, and to the SRP receptor in the ER membrane. | 81 |
| GO:0006626 | protein targeting to mitochondrion | The process of directing proteins towards and into the mitochondrion, usually mediated by mitochondrial proteins that recognize signals contained within the imported protein. | 32 |
| GO:0000060 | protein import into nucleus, translocation | A protein transport process that contributes to protein import into the nucleus, and that results in the vectorial transfer of a cargo-carrier protein complex through the nuclear pore complex from the cytoplasmic side to the nucleoplasmic side of the nuclear envelope. | 31 |
| GO:0006616 | SRP-dependent cotranslational protein targeting to membrane, translocation | The process during cotranslational membrane targeting wherein proteins move across a membrane. SRP and its receptor initiate the transfer of the nascent chain across the endoplasmic reticulum (ER) membrane; they then dissociate from the chain, which is transferred to a set of transmembrane proteins, collectively called the translocon. Once the nascent chain translocon complex is assembled, the elongating chain passes directly from the large ribosomal subunit into the centers of the translocon, a protein-lined channel within the membrane. The growing chain is never exposed to the cytosol and does not fold until it reaches the ER lumen. | 24 |
| GO:0006606 | protein import into nucleus | The directed movement of a protein from the cytoplasm to the nucleus. | 21 |
| GO:0045046 | protein import into peroxisome membrane | The targeting of proteins into the peroxisomal membrane. The process is not well understood, but both signals and mechanism differ from those involved in peroxisomal matrix protein import. | 16 |
| GO:0006623 | protein targeting to vacuole | The process of directing proteins towards the vacuole, usually using signals contained within the protein. | 15 |
| GO:0072661 | protein targeting to plasma membrane | The process of directing proteins towards the plasma membrane; usually uses signals contained within the protein. | 11 |
| GO:0045040 | protein import into mitochondrial outer membrane | The process comprising the insertion of proteins from outside the organelle into the mitochondrial outer membrane, mediated by large outer membrane translocase complexes. | 10 |
| GO:0006612 | protein targeting to membrane | The process of directing proteins towards a membrane, usually using signals contained within the protein. | 10 |
| GO:0006607 | NLS-bearing substrate import into nucleus | The directed movement of a protein bearing a nuclear localization signal (NLS) from the cytoplasm into the nucleus, across the nuclear membrane. | 10 |
| GO:0032258 | CVT pathway | A constitutive biosynthetic process that occurs under nutrient-rich conditions, in which two resident vacuolar hydrolases, aminopeptidase I and alpha-mannosidase, are sequestered into vesicles; these vesicles are transported to, and then fuse with, the vacuole. This pathway is mostly observed in yeast. | 8 |
| GO:0006622 | protein targeting to lysosome | The process of directing proteins towards the lysosome using signals contained within the protein. | 6 |
| GO:0043328 | protein targeting to vacuole involved in ubiquitin-dependent protein catabolic process via the multivesicular body sorting pathway | The process of directing proteins towards the vacuole using signals contained within the protein, occurring that contributes to protein catabolism via the multivesicular body (MVB) pathway. | 6 |
| GO:0006610 | ribosomal protein import into nucleus | The directed movement of a ribosomal protein from the cytoplasm into the nucleus, across the nuclear membrane. | 5 |
| GO:0051531 | NFAT protein import into nucleus | The directed movement of NFAT (nuclear factor of activated T cells) proteins, a family of transcription factors, from the cytoplasm into the nucleus. NFAT proteins are dephosphorylated in the cytoplasm by activated calcineurin, which leads to their translocation across the nuclear membrane. | 4 |
| GO:0007184 | SMAD protein import into nucleus | The directed movement of a SMAD proteins from the cytoplasm into the nucleus. Pathway-restricted SMAD proteins and common-partner SMAD proteins are involved in the transforming growth factor beta receptor signaling pathways. | 4 |
| GO:0030150 | protein import into mitochondrial matrix | The import of proteins across the outer and inner mitochondrial membranes into the matrix. Unfolded proteins enter the mitochondrial matrix with a chaperone protein; the information required to target the precursor protein from the cytosol to the mitochondrial matrix is contained within its N-terminal matrix-targeting sequence. Translocation of precursors to the matrix occurs at the rare sites where the outer and inner membranes are close together. | 4 |
| GO:0016558 | protein import into peroxisome matrix | The import of proteins into the peroxisomal matrix. A peroxisome targeting signal (PTS) binds to a soluble receptor protein in the cytosol, and the resulting complex then binds to a receptor protein in the peroxisome membrane and is imported. The cargo protein is then released into the peroxisome matrix. | 3 |
| GO:0042991 | transcription factor import into nucleus | The directed movement of a transcription factor from the cytoplasm to the nucleus. | 3 |
| GO:0006627 | protein processing involved in protein targeting to mitochondrion | The cleavage of peptide bonds in proteins, usually near the N terminus, contributing to the process of import into the mitochondrion. Several different peptidases mediate cleavage of proteins destined for different mitochondrial compartments. | 3 |
| GO:0045041 | protein import into mitochondrial intermembrane space | The import of proteins into the space between the inner and outer mitochondrial membranes. | 3 |
| GO:0000189 | MAPK import into nucleus | The directed movement of a MAP kinase to the nucleus upon activation. | 3 |
| GO:0006617 | SRP-dependent cotranslational protein targeting to membrane, signal sequence recognition | The process in which SRP binds to the signal peptide in a nascent protein, causing protein elongation to pause, during cotranslational membrane targeting. | 2 |
| GO:0000042 | protein targeting to Golgi | The process of directing proteins towards the Golgi; usually uses signals contained within the protein. | 2 |
| GO:0007262 | STAT protein import into nucleus | The directed movement of dimerized STAT (Signal Transducers and Activators of Transcription) proteins into the nucleus following activation by members of the janus activated kinase (JAK) family of tyrosine kinases. | 2 |
| GO:0045039 | protein import into mitochondrial inner membrane | The process comprising the import of proteins into the mitochondrion from outside the organelle and their insertion into the mitochondrial inner membrane. The translocase of the outer membrane complex mediates the passage of these proteins across the outer membrane, after which they are guided by either of two inner membrane translocase complexes into their final destination in the inner membrane. | 2 |
| GO:0035048 | splicing factor protein import into nucleus | The directed movement of a pre-mRNA splicing factor from the cytoplasm into the nucleus, across the nuclear membrane. | 1 |
| GO:0045047 | protein targeting to ER | The process of directing proteins towards the endoplasmic reticulum (ER) using signals contained within the protein. One common mechanism uses a 16- to 30-residue signal sequence, typically located at the N-terminus of the protein and containing positively charged amino acids followed by a continuous stretch of hydrophobic residues, which directs the ribosome to the ER membrane and initiates transport of the growing polypeptide across the ER membrane. | 1 |
| GO:0006620 | posttranslational protein targeting to membrane | The targeting of proteins to a membrane that occurs after their translation. Some secretory proteins exhibit posttranslational transport into the endoplasmic reticulum (ER) lumen: they are synthesized in their entirety on free cytosolic ribosomes and then released into the cytosol, where they are bound by chaperones which keep them in an unfolded state, and subsequently are translocated across the ER membrane. | 1 |
| GO:0000059 | protein import into nucleus, docking | A protein complex assembly process that contributes to protein import into the nucleus, and that results in the association of a cargo protein, a carrier protein such as an importin alpha/beta heterodimer, and a nucleoporin located at the periphery of the nuclear pore complex. | 1 |
