Protein RD3; Plays a critical role in the regulation of enzymes involved in nucleotide cycle in photoreceptors. Inhibits the basal catalytic activity and the GCAP-stimulated activity of GUCY2D and GUCY2F, two retinal guanylyl cyclases involved in the production of cGMP in photoreceptors. Involved in the transport of GUCY2D and GUCY2F to their target sites in the photoreceptor outer segment. Up-regulates the activity of GUK1, a kinase that plays also an essential role for recycling GMP and indirectly, cGMP. Plays an important role for the survival of rods and cones in the retina (By sim [...]

MORN repeat containing 5.

Aryl-hydrocarbon-interacting protein-like 1; May be important in protein trafficking and/or protein folding and stabilization.

Spermatogenesis-associated protein 7; Involved in the maintenance of both rod and cone photoreceptor cells (By similarity). It is required for recruitment and proper localization of RPGRIP1 to the photoreceptor connecting cilium (CC), as well as photoreceptor-specific localization of proximal CC proteins at the distal CC (By similarity). Maintenance of protein localization at the photoreceptor-specific distal CC is essential for normal microtubule stability and to prevent photoreceptor degeneration (By similarity).

Intraflagellar transport protein 140 homolog; Component of the IFT complex A (IFT-A), a complex required for retrograde ciliary transport and entry into cilia of G protein- coupled receptors (GPCRs). Plays a pivotal role in proper development and function of ciliated cells through its role in ciliogenesis and/or cilium maintenance. Required for the development and maintenance of the outer segments of rod and cone photoreceptor cells. Plays a role in maintenance and the delivery of opsin to the outer segment of photoreceptor cells (By similarity).

Lamin tail domain containing 1.

Inward rectifier potassium channel 13; Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. KCNJ13 has a very low single channel conductance, low sensitivity to block by external barium and cesium, and no dependen [...]

Leucine-rich repeat-containing protein 74B; Leucine rich repeat containing 74B.

Leucine-rich repeat-containing protein 18; May be involved in the regulation of spermatogenesis and sperm maturation.
