potassium voltage-gated channel, subfamily H (eag-related), member 1
Synonyms
Eag1
ether a go-go
Biotype
protein coding gene
Automated Description
Enables delayed rectifier potassium channel activity and voltage-gated monoatomic ion channel activity involved in regulation of presynaptic membrane potential. Involved in potassium ion transmembrane transport; regulation of presynaptic cytosolic calcium ion concentration; and regulation of synaptic vesicle exocytosis. Located in plasma membrane. Is active in parallel fiber to Purkinje cell synapse. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and integumental system. Human ortholog(s) of this gene implicated in colorectal adenocarcinoma. Orthologous to human KCNH1 (potassium voltage-gated channel subfamily H member 1).
MGI Description
PHENOTYPE: Homozygous mutant mice exhibit a decreased depressive-like response during tail suspension testing. Mice homozygous for a different knock-out allele exhibit longer latency to move in haloperidol-treated mice and mild hyperactivity. [provided by MGI curators]
