Gene: SAG (S-antigen visual arrestin) Homo sapiens
Symbol: SAG
Name: S-antigen visual arrestin
Description: Predicted to have G protein-coupled receptor binding activity and spectrin binding activity. Predicted to be involved in G protein-coupled receptor internalization. Localizes to photoreceptor outer segment. Implicated in Oguchi disease-1; hereditary night blindness; and retinitis pigmentosa 47.
Type: protein-coding
RefSeq Status: REVIEWED

NCBI Annotation Information: Note: SAG (Gene ID: 6295) and RNF7 (Gene ID: 9616) share the SAG symbol/alias in common. SAG is a widely used alternative name for ring finger protein 7 (RNF7), which can be confused with the official symbol for SAG (S-antigen visual arrestin, GeneID 6295). [01 Jun 2018]
