Protein: Serine/threonine-protein phosphatase with EF-hands 2 (PPEF-2) (EC 3.1.3.16) (O14830)
Organism: Homo sapiens (Human)
Function: 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 location: Cytoplasm {ECO:0000305}. Cell projection, cilium, photoreceptor outer segment. Photoreceptor inner segment. Note=Localized to photoreceptors, PPEF-2(L) is at least 2 fold more abundant in rod inner segments than in the outer segments.
