Gene: Kcnk3 (potassium two pore domain channel subfamily K member 3) Rattus norvegicus
Symbol: Kcnk3
Name: potassium two pore domain channel subfamily K member 3
RGD ID: 61997
Description: Enables open rectifier potassium channel activity. Involved in several processes, including cellular response to zinc ion; positive regulation of voltage-gated potassium channel activity; and regulation of resting membrane potential. Predicted to be located in plasma membrane. Used to study pulmonary hypertension and pulmonary venoocclusive disease. Biomarker of status epilepticus. Human ortholog(s) of this gene implicated in primary pulmonary hypertension. Orthologous to human KCNK3 (potassium two pore domain channel subfamily K member 3); INTERACTS WITH 17alpha-ethynylestradiol; 2,3,7,8-tetrachlorodibenzodioxine; 4,4'-sulfonyldiphenol.
Type: protein-coding
Previously known as: acid-sensitive potassium channel protein TASK-1; potassium channel subfamily K member 3; potassium channel, subfamily K, member 3; potassium channel, two pore domain subfamily K, member 3; rTASK; Task-1; TWIK-related acid-sensitive K(+) channel 1; TWIK-related acid-sensitive K+ channel; two pore K(+) channel KT3.1; two pore potassium channel KT3.1
