MGI Phenotype

FUNCTION: This gene encodes the slow skeletal tropomyosin-binding subunit of the troponin complex and plays an essential role in the regulation of striated muscle contraction. In humans, mutations in this gene are associated with nemaline myopathy type 5. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Apr 2013]
PHENOTYPE: Mice homozygous for a null or hypomorphic allele show small and loss of type I slow skeletal muscle fibers with compensatory hypertrophy of type II fast fibers and reduced contractile force and tolerance of skeletal muscle fibers. [provided by MGI curators]
