MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is the tropomyosin-binding subunit of the troponin complex, which is located on the thin filament of striated muscles and regulates muscle contraction in response to alterations in intracellular calcium ion concentration. Mutations in this gene have been associated with familial hypertrophic cardiomyopathy as well as with dilated cardiomyopathy. Transcripts for this gene undergo alternative splicing that results in many tissue-specific isoforms, however, the full-length nature of some of these variants has not yet been determined. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a null allele exhibit embryonic lethality during and prior to organogenesis and abnormal heart development. Mice homozygous for an allele that lacks the lysine residue at position 210 exhibit dilated cardiomyopathy. [provided by MGI curators]
