UniProt data

UniProt name: R9BP_HUMAN (Q6ZS82)

Gene name: RGS9BP; Synonyms=R9AP

Organism: Homo sapiens (Human).

Function: Regulator of G protein-coupled receptor (GPCR) signaling in phototransduction. Participates in the recovery phase of visual transduction via its interaction with RGS9-1 isoform. Acts as a membrane-anchor that mediates the targeting of RGS9-1 to the photoreceptor outer segment, where phototransduction takes place. Enhances the ability of RGS9-1 to stimulate G protein GTPase activity, allowing the visual signal to be terminated on the physiologically time scale. It also controls the proteolytic stability of RGS9-1, probably by protecting it from degradation (By similarity). {ECO:0000250}.

Subcellular location: Membrane {ECO:0000250}; Single-pass type IV membrane protein {ECO:0000250}.

Transmembrane domains:

1. 211-231, 21 AA, Helical; Anchor for type IV membrane protein. {ECO:0000255}.

Sequence: 235 AA
