Previous GeneCards Identifiers for KCNK2 Gene
This gene encodes one of the members of the two-pore-domain background potassium channel protein family. This type of potassium channel is formed by two homodimers that create a channel that leaks potassium out of the cell to control resting membrane potential. The channel can be opened, however, by certain anesthetics, membrane stretching, intracellular acidosis, and heat. Three transcript variants encoding different isoforms have been found for this gene.

GeneCards Summary for KCNK2 Gene
KCNK2 (Potassium Channel, Two Pore Domain Subfamily K, Member 2) is a Protein Coding gene. Among its related pathways are Activation of cAMP-Dependent PKA and Activation of cAMP-Dependent PKA. GO annotations related to this gene include outward rectifier potassium channel activity. An important paralog of this gene is KCNK3.
UniProtKB/Swiss-Prot for KCNK2 Gene
Reversibly converts between a voltage-insensitive potassium leak channel and a voltage-dependent outward rectifying potassium channel in a phosphorylation-dependent manner.
Isoform 4: Does not display channel activity but reduces the channel activity of isoform 1 and isoform 2 and reduces cell surface expression of isoform 2.
