RPSBLAST alignment for GI: 254780822 and conserved domain: cd02988
>gnl|CDD|48537 cd02988, Phd_like_VIAF, Phosducin (Phd)-like family, Viral inhibitor of apoptosis (IAP)-associated factor (VIAF) subfamily; VIAF is a Phd-like protein that functions in caspase activation during apoptosis. It was identified as an IAP binding protein through a screen of a human B-cell library using a prototype IAP. VIAF lacks a consensus IAP binding motif and while it does not function as an IAP antagonist, it still plays a regulatory role in the complete activation of caspases. VIAF itself is a substrate for IAP-mediated ubiquitination, suggesting that it may be a target of IAPs in the prevention of cell death. The similarity of VIAF to Phd points to a potential role distinct from apoptosis regulation. Phd functions as a cytosolic regulator of G protein by specifically binding to G protein betagamma (Gbg)-subunits. The C-terminal domain of Phd adopts a thioredoxin fold, but it does not contain a CXXC motif. Phd interacts with G protein beta mostly through the N-terminal helical domain.. Length = 192
