Protein Structure

UniProt Annotation

Function

E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of NUMB. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Mediates ubiquitination of isoform p66 and isoform p72 of NUMB, but not that of isoform p71 or isoform p65.Isoform 2 provides an endocytic scaffold for IGSF5/JAM4.

Subcellular Localization

Cytoplasm.

Disease Associations

Tissue Specificity

Isoform 1 and isoform 2 are expressed in the heart. Isoform 1 is also expressed in kidney, lung and skeletal muscle while isoform 2 is also expressed in brain. {ECO:0000269PubMed:9535908}.
