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.
Interacts with DNAJB12 and DNAJB14; chaperones DNAJB12 and DNAJB14 promote tetramerization (By similarity). Heteromultimer with KCNH6/ERG2 and KCNH7/ERG3 (By similarity).
Interacts with ALG10B (By similarity). Heteromultimer with KCNE1 and KCNE2.
Interacts with CANX. The core-glycosylated, but not the fully glycosylated form interacts with RNF207.
Interacts with NDFIP1 and NDFIP2 (By similarity).
