General description

WW2 (atrophin-1-interacting protein 2) is a member of a large family of NEDD4-like E3 ligases that transfer ubiquitin from E2 ubiquitin-conjugating enzymes to targeted protein substrates. In general, ubiquitination affects protein turnover and activity. As a result, ubiquitin-related enzymes play essential roles in many cellular processes. The WW2 E3 ubiquitin-protein ligase contains a C2 domain at the N-terminus and a HECT (E6AP-type E3 ubiquitin-protein ligase) domain at the C-terminus which interact to inhibit its catalytic activity. Previous studies have suggested that WW2 may play a role in cellular transport, transcription, and T-cell activation. It has also been shown that WW2 regulates the PTEN tumor suppressor and plays an essential role in apoptosis and survival of cancer cells. WW2-deficient mice show abnormal development of craniofacial structures.
