Also known as THIK-2THIK2K2p12.1
Summary
KCNK12 (potassium two pore domain channel subfamily K member 12, HGNC:6274) is a protein-coding gene on chromosome 2p16.3, encoding Potassium channel subfamily K member 12 (Q9HB15). K(+) channel subunit that may homo- and heterodimerize to form functional channels with distinct regulatory and gating properties.
This gene encodes one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. The product of this gene has not been shown to be a functional channel, however, it may require other non-pore-forming proteins for activity.

Potassium channel subfamily K member 12 — Q9HB15 (reviewed: Q9HB15)
Alternative names: Tandem pore domain halothane-inhibited potassium channel 2
All UniProt accessions (1): Q9HB15
UniProt curated annotations — full annotation on UniProt →
Function. K(+) channel subunit that may homo- and heterodimerize to form functional channels with distinct regulatory and gating properties. Can heterodimerize with KCNK13 subunit to conduct K(+) outward rectifying currents at the plasma membrane. The homodimers are mainly retained in the endoplasmic reticulum compartment and may be targeted to the cell surface upon phosphorylation or other activation signals yet to be elucidated.
Subunit / interactions. Homodimer. Heterodimer with KCNK13.
Subcellular location. Cell membrane. Endoplasmic reticulum membrane.
Domain organisation. Each subunit contributes two pore-forming domains 1 and 2 which assemble to form a single pore with M2 and M4 transmembrane helices lining the central cavity and M1 and M3 facing the lipid bilayer. The transmembrane helices are bridged by the selectivity filters 1 and 2 that coordinate the permeant ions. Up to four ions can simultaneously occupy the selectivity filter and at least two elementary charges must translocate across the filter to convert it into the open conformation.
Similarity. Belongs to the two pore domain potassium channel (TC 1.A.1.8) family.
