NEDD4

Also known as NEDD4-1, RPF1, neural precursor cell expressed, developmentally down-regulated 4, E3 ubiquitin protein ligase, NEDD4 E3 ubiquitin protein ligase

E3 ubiquitin-protein ligase NEDD4, also known as neural precursor cell expressed developmentally down-regulated protein 4 (whence "NEDD4") is an enzyme that is, in humans, encoded by the NEDD4 gene.

This gene is the founding member of the NEDD4 family of HECT ubiquitin ligases that function in the ubiquitin proteasome system of protein degradation. The encoded protein contains an N-terminal calcium and phospholipid binding C2 domain followed by multiple tryptophan-rich WW domains and, a C-terminal HECT ubiquitin ligase catalytic domain. It plays critical role in the regulation of a number of membrane receptors, endocytic machinery components and the tumor suppressor PTEN. [provided by RefSeq, Jul 2016].

E3 ubiquitin-protein ligase NEDD4, also known as neural precursor cell expressed developmentally down-regulated protein 4 (whence "NEDD4") is an enzyme that is, in humans, encoded by the NEDD4 gene.

NEDD4 is an E3 ubiquitin ligase enzyme, that targets proteins for ubiquitination. NEDD4 is, in eukaryotes, a highly conserved gene, and the founding member of the NEDD4 family of E3 HECT ubiquitin ligases, which in humans consists of 9 members: NEDD4 (the core topic of this article) NEDD4-2 (or NEDD4L) ITCH SMURF1 SMURF2 WWP1 WWP2 NEDL1 (HECW1) NEDDL2 (HECW2)].
