Short description: Protein-coding gene in the species Homo sapiens

Generic protein structure example

Potassium voltage-gated channel subfamily G member 3 is a protein that in humans is encoded by the KCNG3 gene.^[1]^[2] The protein encoded by this gene is a voltage-gated potassium channel subunit.^[2]
