Background
This gene encodes a protein that contains multiple transmembrane regions and two pore-forming P domains and functions as a pH-dependent potassium channel. Amplification and overexpression of this gene have been observed in several types of human carcinomas. This gene is imprinted in the brain, with preferential expression from the maternal allele. A mutation in this gene was associated with Birk-Barel mental retardation dysmorphism syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013],
Function
disease:Defects in KCNK9 may be the cause of a syndrome of mental retardation, hypotonia, and facial dysmorphism; also known as Birk Barel syndrome.,disease:Overexpressed in a high proportion of breast cancers. May confer resistance to growth factor deprivation and hypoxia, thereby promoting tumor cell survival in poorly oxygenated areas of solid tumors.,function:pH-dependent, voltage-insensitive, background potassium channel protein.,miscellaneous:Inhibited by phorbol 12-myristate 13-acetate (PMA). TASK-3 current is strongly decreased in the presence of an extracellular pH inferior to 7.0.,similarity:Belongs to the two pore domain potassium channel (TC 1.A.1.8) family.,tissue specificity:Mainly found in the cerebellum. Also found in adrenal gland, kidney and lung.,
