CC -!- FUNCTION: E3 ubiquitin-protein ligase that mediates ubiquitination oF
CC target proteins (By similarity). Depending on the associated E2 ligase,
CC mediates 'Lys-48'- and 'Lys-63'-linked polyubiquitination of substrates
CC (PubMed:23418353). Part of a BAG6-dependent quality control process
CC ensuring that proteins of the secretory pathway that are mislocalized
CC to the cytosol are degraded by the proteasome (By similarity). Probably
CC acts by providing the ubiquitin ligase activity associated with the
CC BAG6 complex and be responsible for ubiquitination of the hydrophobic
CC mislocalized proteins and their targeting to the proteasome (By
CC similarity). May also play a role in the endosomal recycling of IGF2R,
CC the cation-independent mannose-6-phosphate receptor (By similarity).
CC May play a role in the endosomal sorting and degradation of several
CC membrane receptors including EGFR, FLT3, MET and CXCR4, by mediating
CC their ubiquitination (PubMed:23418353). By ubiquitinating CDKN1A/p21
CC and targeting it for degradation, may also promote cell proliferation
CC (By similarity). May monoubiquitinate AICDA (By similarity).
CC {ECO:0000250|UniProtKB:Q9BV68, ECO:0000269|PubMed:23418353}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC EC=2.3.2.27; Evidence={ECO:0000269|PubMed:23418353};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000269|PubMed:23418353}.
CC -!- SUBUNIT: Interacts with CCDC50, EGFR, FLT3 and SCAMP3
CC (PubMed:23418353). Interacts with BAG6 (via ubiquitin-like domain);
CC required for BAG6-dependent ubiquitination of proteins mislocalized to
CC the cytosol (By similarity). Interacts with CDKN1A (By similarity).
CC Interacts with AICDA (By similarity). {ECO:0000250|UniProtKB:Q9BV68,
CC ECO:0000269|PubMed:23418353}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9BV68}. Nucleus
CC {ECO:0000250|UniProtKB:Q9BV68}.
CC -!- TISSUE SPECIFICITY: Detected in B-cells (at protein level).
CC {ECO:0000269|PubMed:23277564}.
CC -!- INDUCTION: Up-regulated in B-cells that undergo class-switch
CC recombination (at protein level). {ECO:0000269|PubMed:23277564}.
CC -!- DOMAIN: The C4-type zinc finger is required for interaction with BAG6.
CC {ECO:0000250|UniProtKB:Q9BV68}.
CC -!- PTM: Ubiquitinated. May undergo autoubiquitination.
