Function

Activates HECT domain-containing several E3 ubiquitin- protein ligases, including NEDD4 and ITCH, and consequently modulates the stability of their targets. As a result, controls many cellular processes. Prevents chronic T-helper cells-mediated inflammation by activating ITCH and thus controlling JUNB degradation. In cortical neurons, mediates the ubiquitination of SLC11A2/DMT1 by NEDD4L, leading to down-regulation of the divalent metal transporter and protection of the cells from cobalt and iron toxicity (By similarity). Modulates EGFR signaling through multiple pathways. In particular, may regulate the ratio of AKT1- to-MAPK8 signaling in response to EGF, acting on AKT1 probably through PTEN destabilization and on MAPK8 through ITCH-dependent MAP2K4 inactivation. As a result, may control cell growth rate (By similarity). {ECO:0000250}.

Subcellular Localization

Endosome membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Golgi apparatus membrane {ECO:0000269PubMed:11748237, ECO:0000269PubMed:16822981, ECO:0000269PubMed:18819914}. Secreted {ECO:0000250}. Note=Detected in exosomes and secreted via the exosomal pathway. {ECO:0000250}.

Disease Associations

Tissue Specificity

Widely expressed. Hardly detectable in resting T-cells; up-regulated in T-cells in response to activation. {ECO:0000269PubMed:11748237, ECO:0000269PubMed:17137798}.
