CACNG8 (Calcium Voltage-Gated Channel Auxiliary Subunit Gamma 8) is a Protein Coding gene. Diseases associated with CACNG8 include Dilated Cardiomyopathy. Among its related pathways are Arrhythmogenic right ventricular cardiomyopathy (ARVC) and Fc-GammaR Pathway. The protein encoded by CACNG8 is a type I transmembrane AMPA receptor regulatory protein (TARP). TARPs regulate both trafficking and channel gating of the AMPA receptors. CACNG8 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. The mRNA for CACNG8 is believed to initiate translation from a non-AUG (CUG) start codon.
