RPGR - retinitis pigmentosa GTPase regulator Gene
Also Known as CRD; RP3; COD1; PCDX; RP15; XLRP3; orf15; CORDX1
Species: Homo sapiens
About RPGR
This gene has 19 transcripts (splice variants), 259 orthologues, 9 paralogues and is associated with 11 phenotypes. Ubiquitous expression in testis (RPKM 2.6), lung (RPKM 2.3) and 25 other tissues.
Summary
This gene encodes a protein with a series of six RCC1-like domains (RLDs), characteristic of the highly conserved guanine nucleotide exchange factors. The encoded protein is found in the Golgi body and interacts with RPGRIP1. This protein localizes to the outer segment of rod photoreceptors and is essential for their viability. Mutations in this gene have been associated with X-linked retinitis pigmentosa (XLRP). Multiple alternatively spliced transcript variants that encode different isoforms of this gene have been reported, but the full-length natures of only some have been determined.
