Description: This gene encodes a voltage-activated potassium channel belonging to the eag family. It shares sequence similarity with the Drosophila ether-a-go-go (eag) gene. Mutations in this gene can cause long QT syndrome type 2 (LQT2). Transcript variants encoding distinct isoforms have been identified. Pore-forming (alpha) subunit of voltage-gated inwardly rectifying potassium channel. Channel properties are modulated by cAMP and subunit assembly. Mediates the rapidly activating component of the delayed rectifying potassium current in heart (IKr). Isoform 3 has no channel activity by itself, but modulates channel characteristics when associated with isoform 1.
Function: Pore-forming (alpha) subunit of voltage-gated inwardly rectifying potassium channel. Channel properties are modulated by cAMP and subunit assembly. Mediates the rapidly activating component of the delayed rectifying potassium current in heart (IKr) (PubMed:18559421, PubMed:26363003, PubMed:27916661).
Subunit Structure: The potassium channel is probably composed of a homo-or heterotetrameric complex of pore-forming alpha subunits that can associate with modulating beta subunits (PubMed:27916661). Interacts with DNAJB12 and DNAJB14; chaperones DNAJB12 and DNAJB14 promote tetramerization (PubMed:27916661). Heteromultimer with KCNH6/ERG2 and KCNH7/ERG3 (By similarity). Interacts with ALG10B (By similarity). Heteromultimer with KCNE1 and KCNE2 (PubMed:9230439, PubMed:10219239). Interacts with CANX (PubMed:16361248). The core-glycosylated, but not the fully glycosylated form interacts with RNF207 (PubMed:25281747). Interacts with NDFIP1 and NDFIP2 (PubMed:26363003).
Post-translational Modifications: Phosphorylated on serine and threonine residues. Phosphorylation by PKA inhibits ion conduction.
Similarity: The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position. Belongs to the potassium channel family. H (Eag) (TC 1.A.1.20) subfamily. Kv11.1/KCNH2 sub-subfamily.
