Function
GRK7 was detected in the apical side of cilia and OS-like structures, colocalizing with PRPH2. EYS plays a role in the trafficking of an OS protein, G protein–coupled receptor kinase 7 (GRK7), which is evolutionarily conserved along with EYS and involved in photoresponse recovery (27, 28). EYS-RD organoids and zebrafish exhibited light-induced photoreceptor cell death related to GRK7 deprivation in the OS. Furthermore, light-induced cell death in RD organoids was especially caused by blue light(PMID: 38646933, 36273582).; Mutations in GRK7 cause Retinal Dystrophy (PMID: 38646933).
Model organism evidence
This causes elongation of motile cilia in the organ of laterality, a consequence that is known to be sufficient to trigger aberrant organ arrangement.
