FunctionMay play a role in phototransduction. May dephosphorylate photoactivated rhodopsin. May function as a calcium sensing regulator of ionic currents, energy production or synaptic transmission.
Tissue specificityRetinal specific.
Sequence similaritiesBelongs to the PPP phosphatase family. Contains 3 EF-hand domains. Contains 1 IQ domain.
Cellular localizationCytoplasm. 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.
