MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an intracellular calcium-binding protein belonging to the troponin C superfamily. Members of this protein family have six EF-hand domains which bind calcium. This protein plays a role in diverse cellular functions, including message targeting and intracellular calcium buffering. It also functions as a modulator of neuronal excitability, and is a diagnostic marker for some human diseases, including Hirschsprung disease and some cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2010]
PHENOTYPE: Homozygous targeted mutants showed normal growth, normal brain histology, and generally normal behavior. Impaired motor coordination was observed in wheel running in young and old mutant mice, and progressive impairment was seen on the runway and horizontal stationary rod tests in older mice. Abnormalities are observed in Purkinje cell firing, altering both simple and complex spikes. [provided by MGI curators]
