Calcium-binding protein that interacts with newly synthesized glycoproteins in the endoplasmic reticulum. It may act in assisting protein assembly and/or in the retention within the ER of unassembled protein subunits. It seems to play a major role in the quality control apparatus of the ER by the retention of incorrectly folded proteins. Required for embryogenesis and larval development under heat and ER stress conditions. May be important for germ cell development. Involved in neuronal necrotic cell death.

Partial T-cell antigen receptor complexes can escape the ER of immature thymocytes in association with their molecular chaperone to be expressed at low levels on the cell surface where they may function as a signaling complex to regulate thymocyte maturation.

Numb is a membrane associated adaptor protein which plays critical roles in cell fate determination. Numb proteins are involved in control of asymmetric cell division and cell fate choice, endocytosis, cell adhesion, cell migration, ubiquitination of specific substrates and a number of signaling pathways (Notch, Hedgehog, p53). Mutations in Numb plays a critical role in disease (cancer). Numb has an N-terminal PTB domain and a C-terminal NumbF domain. PTB domains have a common PH-like fold and are found in various eukaryotic signaling molecules. This domain was initially shown to binds peptides with a NPXY motif with differing requirements for phosphorylation of the tyrosine, although more recent studies have found that some types of PTB domains can bind to peptides lack tyrosine residues altogether. In contrast to SH2 domains, which recognize phosphotyrosine and adjacent carboxy-terminal residues, PTB-domain binding specificity is conferred by residues amino-terminal to the phosphotyrosine. PTB domains are classified into three groups: phosphotyrosine-dependent Shc-like, phosphotyrosine-dependent IRS-like, and phosphotyrosine-independent Dab-like PTB domains. This cd is part of the Dab-like subgroup. Length = 135
>PF00262 Calreticulin: Calreticulin family; InterPro: IPR001580 Synonym(s): Calregulin, CRP55, HACBP Calreticulin [] is a high-capacity calcium-binding protein which is present in most tissues and located at the periphery of the endoplasmic (ER) and the sarcoplamic reticulum (SR) membranes
It probably plays a role in the storage of calcium in the lumen of the ER and SR and it may well have other important functions. Structurally, calreticulin is a protein of about 400 amino acid residues consisting of three domains: An N-terminal, probably globular, domain of about 180 amino acid residues (N-domain). A central domain of about 70 residues (P-domain) which contains three repeats of an acidic 17 amino acid motif. This region binds calcium with a low-capacity, but a high-affinity. A C-terminal domain rich in acidic residues and in lysine (C-domain). This region binds calcium with a high-capacity but a low-affinity. Calreticulin is evolutionarily related to several other calcium-binding proteins, including Onchocerca volvulus antigen RAL-1, calnexin [] and calmegin [].; GO: 0005509 calcium ion binding; PDB: 3POS_C 3DOW_B 3POW_A 1HHN_A 1K9C_A 1K91_A 3O0X_B 3O0W_A 3RG0_A 3O0V_A ....
