Sag - S-antigen, retina and pineal gland (arrestin) Gene

Also Known as Arr1; Irbp; arrestin; A930001K18Rik

Species: Mus musculus

Gene Type: protein coding
Gene ID: 20215

Summary

Enables opsin binding activity and phosphoprotein binding activity. Predicted to be involved in G protein-coupled receptor internalization. Located in photoreceptor inner segment and photoreceptor outer segment. Is expressed in eye and retina outer nuclear layer. Human ortholog(s) of this gene implicated in Oguchi disease-1; hereditary night blindness; and retinitis pigmentosa 47. Orthologous to human SAG (S-antigen visual Arrestin).
