MGI Phenotype FUNCTION: This gene encodes a member of the Slo potassium channel family that has shown to be activated by both sodium and chloride ions. This channel represents the largest potassium channel subunit yet identified. This channel may be important in development and pain signaling. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit impaired action potential firing in sensory neurons and increased mechanical hypersensitivity in neuropathic pain models. [provided by MGI curators]
