<p>Retinal rod rhodopsin-sensitive cGMP 3',5'-cyclic phosphodiesterase (<db_xref db="EC" dbkey="3.1.4.17"/>) is an oligomer composed of two catalytic chains (alpha and beta), an inhibitory chain (gamma) and a delta chain. This protein interacts with RPGR (retinitis pigmentosa GTPase regulator) [<cite idref="PUB00042676"/>], ARL2 (Arf-like-2) and ARL3. This entry represents the delta subunit [<cite idref="PUB00042677"/>], which is thought to act as a prenyl-binding protein [<cite idref="PUB00042678"/>].</p> Retinal rod rhodopsin-sensitive cGMP 3', 5'-cyclic phosphodiesterase, delta subunit
