Genes affected

RGS9BP (HGNC:30304): (regulator of G protein signaling 9 binding protein) The protein encoded by this gene functions as a regulator of G protein-coupled receptor signaling in phototransduction. Studies in bovine and mouse show that this gene is expressed only in the retina, and is localized in the rod outer segment membranes. This protein is associated with a heterotetrameric complex, specifically interacting with the regulator of G-protein signaling 9, and appears to function as the membrane anchor for the other largely soluble interacting partners. Mutations in this gene are associated with prolonged electroretinal response suppression (PERRS), also known as bradyopsia. [provided by RefSeq, Mar 2010]

RGS9BP links:

ANKRD27 (HGNC:25310): (ankyrin repeat domain 27) Enables guanyl-nucleotide exchange factor activity and small GTPase binding activity. Involved in endocytic recycling and negative regulation of SNARE complex assembly. Acts upstream of or within early endosome to late endosome transport. Located in endosome; lysosome; and plasma membrane. Implicated in eosinophilic esophagitis. [provided by Alliance of Genome Resources, Apr 2022]
