Gene: Kcnn4 (potassium calcium-activated channel subfamily N member 4) Rattus norvegicus
Symbol: Kcnn4
Name: potassium calcium-activated channel subfamily N member 4
Description: Exhibits Intermediate conductance calcium-activated potassium channel activity. Involved in anion transport and potassium ion export across plasma membrane. Localizes to several cellular components, including apical plasma membrane; basolateral plasma membrane; and membrane raft. Human ortholog(s) of this gene implicated in dehydrated hereditary stomatocytosis 2. Orthologous to human KCNN4 (potassium calcium-activated channel subfamily N member 4); PARTICIPATES IN calcium/calcium-mediated signaling pathway; INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 6-propyl-2-thiouracil; acetamide.
Type: protein-coding
RefSeq Status: VALIDATED
