CAPN3 - calpain 3 Gene
Also Known as p94; CANP3; LGMD2; nCL-1; CANPL3; LGMD2A; LGMDD4; LGMDR1
Species: Homo sapiens
About CAPN3
This gene has 59 transcripts (splice variants), 292 orthologues, 20 paralogues and is associated with 4 phenotypes. Broad expression in bone marrow (RPKM 19.1), kidney (RPKM 13.9) and 24 other tissues.
Summary
Calpain, a heterodimer consisting of a large and a small subunit, is a major intracellular protease, although its function has not been well established. This gene encodes a muscle-specific member of the calpain large subunit family that specifically binds to titin. Mutations in this gene are associated with limb-girdle muscular dystrophies type 2A. Alternate promoters and alternative splicing result in multiple transcript variants encoding different isoforms and some variants are ubiquitously expressed. [provided by RefSeq, Jul 2008]
