Protein

Potassium voltage-gated channel subfamily H member 5

Gene
Kcnh5, Eag2
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

Pore-forming (alpha) subunit of voltage-gated potassium channel. Elicits a non-inactivating outward rectifying current. Channel properties may be modulated by cAMP and subunit assembly.

Expressioni

Tissue specificityi

Detected in adult testis and in embryonic and adult brain, but not in other tissues. Highly expressed in specific brain areas, such as neocortex, olfactory bulb, primary olfactory cortex and brain stem. In cortex, expression is concentrated in a narrow band toward the middle lamella (layer IV). Moderately expressed in spinal cord, dorsal thalamic nuclei, medial hypothalamus, colliculus, lateral lemniscus, pontine nuclei and Islands of Calleja.

Interactioni

Subunit structurei

The potassium channel is probably composed of a homo- or heterotetrameric complex of pore-forming alpha subunits that can associate with modulating beta subunits. Heteromultimer with KCNH1/EAG By similarity.
