SwissProt ID Link P46379
Function Chaperone that plays a key role in various processes such as apoptosis, insertion of tail-anchored (TA) membrane proteins to the endoplasmic reticulum membrane and regulation of chromatin. Key component of the BAG6/BAT3 complex, a cytosolic multiprotein complex involved in the post-translational delivery of tail-anchored (TA) membrane proteins to the endoplasmic reticulum membrane. TA membrane proteins, also named type II transmembrane proteins, contain a single C-terminal transmembrane region. BAG6/BAT3 acts by facilitating TA membrane proteins capture by ASNA1/TRC40: it is recruited to ribosomes synthesizing membrane proteins, interacts with the transmembrane region of newly released TA proteins and transfers them to ASNA1/TRC40 for targeting to the endoplasmic reticulum membrane. Moreover, it regulates the stability and the degradation of proteins by the proteasome. For instance, it is required for selective ubiquitin-mediated degradation of defective nascent chain polypeptides by the proteasome. In this context, may play a role in immuno-proteasomes to generate antigenic peptides via targeted degradation, thereby playing a role in antigen presentation in immune response. It is also involved in ubiquitin-mediated proteasomal degradation of proteins of the secretory pathway that are mislocalized to the cytosol. Binds the mislocalized proteins, preventing their aggregation in the cytosol, and promotes their ubiquitination. Participates in endoplasmic reticulum stress-induced apoptosis via its interaction with AIFM1/AIF by regulating AIFM1/AIF stability and preventing its degradation. Also required during spermatogenesis for synaptonemal complex assembly via its interaction with HSPA2, by inhibiting polyubiquitination and subsequent proteasomal degradation of HSPA2.
Subcellular Location Cytoplasm, cytosol. Nucleus. The C-terminal fragment generated by caspase-3 is cytoplasmic. Also found in extracellular vesicular exosomes in some tumor cells.
Post-Translational Modification Cleavage by caspase-3 releases a C-terminal peptide that plays a role in ricin-induced apoptosis. In case of infection by L.pneumophila, ubiquitinated by the SCF(LegU1) complex.
Subunit Structure Component of the BAT3 complex, at least composed of BAG6/BAT3, UBL4A and GET4/TRC35. Interacts with AIFM1, CTCFL, HSPA2 and p300/EP300. Interacts with ricin A chain. Interacts with L.pneumophila proteins Lpg2160 and LegU1. Interacts with NCR3. Interacts (via ubiquitin-like domain) with RNF126; required for BAG6-dependent ubiquitination of proteins mislocalized to the cytosol.
Sequence Similarities Contains 1 ubiquitin-like domain.
