The protein encoded by CACNG4(calcium voltage-gated channel auxiliary subunit gamma 4) is a type I transmembrane AMPA receptor regulatory protein (TARP). TARPs regulate both trafficking and channel gating of the AMPA receptors. CACNG4 is part of a functionally diverse eight-member protein subfamily of the PMP-22/EMP/MP20 family and is located in a cluster with two family members, a type II TARP and a calcium channel gamma subunit.基因ID为:27092;蛋白质ID:Q9UBN1
