Function

E3 ubiquitin-protein ligase that regulates several biological processes through the ubiquitin-mediated proteasomal degradation of various target proteins. Mediates 'Lys-48'-linked polyubiquitination of PRR5L and its subsequent proteasomal degradation thereby indirectly regulating cell migration through the mTORC2 complex. Also ubiquitinates the caspases CASP8 and CASP10, promoting their proteasomal degradation, to negatively regulate apoptosis downstream of death domain receptors. Also negatively regulates the tumor necrosis factor-mediated signaling pathway through targeting of RIPK1 to ubiquitin-mediated proteasomal degradation. Negatively regulates p53/TP53 through its direct ubiquitination and targeting to proteasomal degradation. Indirectly, may also negatively regulate p53/TP53 through ubiquitination and degradation of SNF. May also play a role in endocytic recycling. {ECO:0000269PubMed:15229288, ECO:0000269PubMed:22609986}.

Subcellular Localization

Cytoplasm, cytosol {ECO:0000269PubMed:15229288}. Cell membrane {ECO:0000269PubMed:15229288}; Peripheral membrane protein {ECO:0000269PubMed:15229288}. Recycling endosome membrane {ECO:0000305PubMed:15229288}; Peripheral membrane protein {ECO:0000305PubMed:15229288}. Note=The FYVE-type zinc finger may mediate phosphatidylinositol phosphate-binding and control subcellular localization.
