Description 

Rabbit polyclonal to Calpain 7 - Carboxyterminal end domain-N

Immunogen 

Synthetic peptide corresponding to the Domain N of the large subunit of Human Calpain 7.(Peptide available as ab41317.)

Reacts with

Hu, Ms, Rat

Specificity 

ab38937 binds to Calpain 7, but does not cross react with the other calpain family members (calpain 1, calpain 2, Calpain 3, ncl 3, etc.). It reacts to the Carboxyterminal end Domain-N of Calpain 7 and recognizes latent and amino-processed Calpain 7.

Recommended dilutions
WB: A recommended starting concentration for Western blots is 1:1000 when using colorimetric substrates such as BCIP/NBT, and 1:5000 for chemiluminescent substrates. Higher concentrations of antibody may be needed for samples from more distantly related species. When used against the reduced protein this antibody identifies bands at 93 Kd, 68 Kd, and a series of further cleaved forms. Dilution optimised using Chromogenic detection. Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user.

Relevance 

Calpain proteinases are defined currently as papain-like neutral proteases that are calcium activated. Calpains 1 and 2 are composed of a large subunit, which is proteolytically active, and a small subunit (also called calpain 4), or enhancer protein, that is not proteolytically active. The other calpain proteins identified to date (Calpain 5, 6, 8, 9, 10, 11, 12, 13, 14, 15) are not known to require a small subunit. Domains in the large subunit include the amino terminal domain-I, the proteinase domain-II, domain-III, and the EF-hand domain-IV (domain-T in calpains 5 & 6, domain-N for calpain 7). Calpain 7 domain-N does not have the standard calpain EF hand domain for binding calcium, making it unclear whether it is calcium regulated. In place of the EF hand calcium-binding domain IV, Calpain 7 has a sequence most closely resembling domain-III, with unknown function. Calpain 7 is widely distributed, found in most tissues analyzed.
