Potassium voltage-gated channel subfamily V member 1

Gene

KCNV1

Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Potassium channel subunit that does not form functional channels by itself. Modulates KCNB1 and KCNB2 channel activity by shifting the threshold for inactivation to more negative values and by slowing the rate of inactivation. Can down-regulate the channel activity of KCNB1, KCNB2, KCNC4 and KCND1, possibly by trapping them in intracellular membranes (By similarity).By similarity
