General annotation (Comments)

Function

Potassium channel subunit. Modulates channel activity by shifting the threshold and the half-maximal activation to more negative values By similarity.

Subunit structure

Heteromultimer with KCNB1, KCNC1 and KCNF1. Does not form homomultimers By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein By similarity.

Domain

The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position By similarity.

Sequence similarities

Belongs to the potassium channel family. G (TC 1.A.1.2) subfamily. Kv6.4/KCNG4 sub-subfamily. [View classification]
