Predicted to enable calcium sensitive guanylate cyclase activator activity. Involved in positive regulation of cGMP-mediated signaling and positive regulation of guanylate cyclase activity. Located in membrane; photoreceptor inner segment; and photoreceptor outer segment. Human ortholog(s) of this gene implicated in cone-rod dystrophy 14. Orthologous to human GUCA1A (guanylate cyclase activator 1A). [provided by Alliance of Genome Resources, Apr 2022]
