X-linked retinitis pigmentosa GTPase regulator-interacting protein 1 is a protein in the ciliary transition zone that in humans is encoded by the RPGRIP1 gene.[5][6] RPGRIP1 is a multi-domain protein containing a coiled-coil domain at the N-terminus, two C2 domains and a C-terminal RPGR-interacting domain (RID). Defects in the gene result in the Leber congenital amaurosis (LCA) syndrome[7] and in the eye disease glaucoma.[8]


RPGRIP1 has been shown to interact with Retinitis pigmentosa GTPase regulator.[9] RPGRIP1 interacts with RPGR via its RPGR-interacting domain (RID), which folds into a C2 domain architecture and interacts with RPGR at three different locations: A β strand of the RID interacting with the large loop of RPGR, at a hydrophobic interaction site, and via the N-terminal region of the RID.[10]
