Function

Expressed in spermatocytes and in the mature reti . Mutations have been associated with Leber Congenital Amaurosis and Retinitis Pigmentosa (19268277). Component of a protein complex which interacts with CETN2 and CETN3 to stabilise the photoreceptor distal connecting cilium and proximal OS axoneme (30647131). Interacts with photoreceptor-specific ciliary proteins RPGR and RPGRIP1 to maintain distal connecting cilium (DCC) structure, it also regulares protein localization into the DCC (29899041).

Spata7 is required for maintenance of the retinal connecting cilium.

BACKGROUND: The spermatogenesis-associated protein-7 (SPATA7) gene encodes a ciliary protein that is expressed in the photoreceptors and in spermatocytes.
