InnateDB Gene

IDBG-48503 (KCNG3)

Protein Structure

UniProt Annotation

Function

Potassium channel subunit. Modulates channel activity.

Subcellular Localization

Cell membrane; Multi-pass membrane protein. Membrane; Multi-pass membrane protein. Note=Has to be associated with KCNB1 or possibly another partner to get inserted in the plasma membrane. Remains intracellular in the absence of KCNB1.

Disease Associations

Tissue Specificity

Detected in many parts of the brain with the exception of the cerebellum, in testis, pancreas, lung, kidney, ovary, small intestine, colon, thymus, adrenal gland and spinal cord.
