The pre-protein translocase of the mitochondrial outer membrane (Tom) allows the import of pre-proteins from the cytoplasm. Tom forms a complex with a number of proteins, including Tim17. Tim17 and Tim23 are thought to form the translocation channel of the inner membrane. This family includes Tim17, Tim22 and Tim23. This family also includes Pmp24 a peroxisomal protein. The involvement of this domain in the targeting of PMP24 remains to be proved. PMP24 was known as Pmp27 in. Length = 128
>PF02466 Tim17: Tim17/Tim22/Tim23/Pmp24 family; InterPro: IPR003397 The membrane-embedded multi-protein complexes of mitochondria mediate the transport of nuclear-encoded proteins across and into the outer or inner mitochondrial membranes []
The TOM (translocase of the outer mitochondrial membrane) complex consists of cytosol-exposed receptors and a pore-forming core, and mediates the transport of proteins from the cytosol across and into the outer mitochondrial membrane. A novel protein complex in the outer membrane of mitochondria, called the SAM complex (sorting and assembly machinery), is involved in the biogenesis of beta-barrel proteins of the outer membrane. Two translocases of the inner mitochondrial membrane (TIM22 and TIM23 complexes) mediate protein transport at the inner membrane. The TIM23 complex (a presequence translocase) mediates the transport of presequence-containing proteins across and into the inner membrane. Tim23 and Tim17 form part of this complex. Tim23 forms a pore in the inner membrane. The role of Tim17 is not yet fully understood. The TIM22 complex (a twin-pore carrier translocase) catalyses the insertion of multi-spanning proteins that have internal targeting signals into the inner membrane. The TIM22 complex mediates the membrane insertion of multi-spanning inner-membrane proteins that have internal targeting signals, and it uses the membrane potential as an external driving force. The Tim22 subunit of the mitochondrial import inner membrane translocase is included in this family. This family also includes Pmp24, a peroxisomal membrane protein, and NADH ubiquinone dehydrogenase 1 alpha subunit 11. Pmp24 was previously known as Pmp27 [].
>PF10247 Romo1: Reactive mitochondrial oxygen species modulator 1; InterPro: IPR018450 The majority of endogenous reactive oxygen species (ROS) in cells are produced by the mitochondrial respiratory chain
An increase or imbalance in ROS alters the intracellular redox homeostasis, triggers DNA damage, and may contribute to cancer development and progression. This entry contains the mitochondrial protein, reactive oxygen species modulator 1 (Romo1), that is responsible for increasing the level of ROS in cells. In various cancer cell lines with elevated levels of ROS there is also an increased abundance of Romo1 []. Increased Romo1 expression can have a number of other affects including: inducing premature senescence of cultured human fibroblasts [, ] and increased resistance to 5-fluorouracil [].
