| Post Translational Modifications | Proteolytically cleaved on its way through the secretory system, probably within the Golgi lumen. Proteolytic cleavage is not necessary for its chaperone activity. All non-secreted forms are not proteolytically cleaved. Chaperone activity of uncleaved forms is dependent on a non-reducing environment. Polyubiquitinated, leading to proteasomal degradation. Under cellular stress, the intracellular level of cleaved form is reduced due to proteasomal degradation. Extensively glycosylated with sulfated N-linked carbohydrates. About 30% of the protein mass is comprised of complex N-linked carbohydrate. Endoplasmic reticulum (ER) stress induces changes in glycosylation status and increases level of hypoglycosylated forms. Core carbohydrates are essential for chaperone activity. Non-secreted forms are hypoglycosylated or unglycosylated. |
| Function | Functions as extracellular chaperone that prevents aggregation of non native proteins. Prevents stress-induced aggregation of blood plasma proteins. Inhibits formation of amyloid fibrils by APP, APOC2, B2M, CALCA, CSN3, SNCA and aggregation-prone LYZ variants (in vitro). Does not require ATP. Maintains partially unfolded proteins in a state appropriate for subsequent refolding by other chaperones, such as HSPA8/HSC70. Does not refold proteins by itself. Binding to cell surface receptors triggers internalization of the chaperone-client complex and subsequent lysosomal or proteasomal degradation. When secreted, protects cells against apoptosis and against cytolysis by complement. Intracellular forms interact with ubiquitin and SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complexes and promote the ubiquitination and subsequent proteasomal degradation of target proteins. Promotes proteasomal degradation of COMMD1 and IKBKB. Modulates NF-kappa-B transcriptional activity. Following stress, promotes apoptosis. Inhibits apoptosis when associated with the mitochondrial membrane by interference with BAX-dependent release of cytochrome c into the cytoplasm. Plays a role in the regulation of cell proliferation. Following ER stress, suppresses stress-induced apoptosis by stabilizing mitochondrial membrane integrity through interaction with HSPA5. When secreted, does not affect caspase or BAX-mediated intrinsic apoptosis and TNF-induced NF-kappa-B-activity. When secreted, acts as an important modulator during neuronal differentiation through interaction with STMN3. Plays a role in the clearance of immune complexes that arise during cell injury. |
