DESCRIPTION

Also known as NOSIP_HUMAN, NOSIP. E3 ubiquitin-protein ligase that is essential for proper development of the forebrain, the eye, and the face. Catalyzes monoubiquitination of serine/threonine-protein phosphatase 2A (PP2A) catalytic subunit PPP2CA/PPP2CB (By similarity). Negatively regulates nitric oxide production by inducing NOS1 and NOS3 translocation to actin cytoskeleton and inhibiting their enzymatic activity (PubMed:11149895, PubMed:15548660, PubMed:16135813). Interacts with NOS1 and NOS3 (PubMed:11149895, PubMed:15548660). Interacts with PP2A holoenzyme, containing PPP2CA, PPP2CB, PPP2R1A and PPP2R2A subunits (By similarity).
