Predicted to enable channel regulator activity and voltage-gated calcium channel activity. Predicted to be involved in several processes, including neurotransmitter receptor transport, postsynaptic endosome to lysosome; postsynaptic neurotransmitter receptor diffusion trapping; and regulation of neurotransmitter receptor activity. Predicted to be located in postsynaptic density. Predicted to be part of AMPA glutamate receptor complex. Predicted to be active in glutamatergic synapse and postsynaptic density membrane. Is expressed in nervous system and retina. Orthologous to human CACNG5 (calcium voltage-gated channel auxiliary subunit gamma 5). [provided by Alliance of Genome Resources, Apr 2022]
