DescriptionAnti-Calpain II Antibody, large subunit
Alternate Names
  • M-Calpain
  • Calpain 2
Background InformationCalpains are cytosolic, calcium-dependent, cysteine proteases that are ubiquitously expressed in mammalian and avian tissues. Calpain-1 and 2 consist of a common small subunit and a large variable subunit. Domains in the large subunit include the amino terminal domain I, the proteinase domain II, domain III, and the EF-hand domain IV.
Type I calpain requires micromolar amounts of calcium, while type II calpain requires millimolar amounts of calcium.

Antibody TypePolyclonal Antibody
Entrez Gene Number
Entrez Gene SummaryThe calpains, calcium-activated neutral proteases, are nonlysosomal, intracellular cysteine proteases. The mammalian calpains include ubiquitous, stomach-specific, and muscle-specific proteins. The ubiquitous enzymes consist of heterodimers with distinct large, catalytic subunits associated with a common small, regulatory subunit. This gene encodes the large subunit of the ubiquitous enzyme, calpain 2. Multiple heterogeneous transcriptional start sites in the 5' UTR have been reported.
