May play a role in phototransduction. May dephosphorylate photoactivated rhodopsin. May function as a calcium sensing regulator of ionic currents, energy production or synaptic transmission.
Subcellular locations: Cytoplasm, Cell projection, Cilium, Photoreceptor outer segment, Photoreceptor inner segment
Localized to photoreceptors, PPEF-2(L) is at least 2 fold more abundant in rod inner segments than in the outer segments.
Retinal specific.
