Gene Information

General description

Lens-specific LP82 and LP85 proteins are localized in the eye tissues of rodents. Muscle-preferred p94 calpain gene encodes for the splice variants, LP82 and LP85. These two proteins are members of the alternative exon 1 (AX1) subclass of calpains.

Specificity

The antibody reacts with latent and active LP-82/LP-85 calpain. By immunoblotting against the reduced protein, the antibody reacts with bands at 85 kDa, 82 kDa, 62 kDa and 60 kDa and a series of further cleaved active forms. It also reacts with non-reduced calpain LP-82/LP-85. The antibody does not cross-react with other calpain family members (μ-calpain, m-calpain, calpain-94, ncl-2, ncl-3, etc.).

Immunogen

synthetic peptide corresponding to the C-terminal of the domain-III in the large subunit of rat LP-82 calpain (lens-specific calpain).

Application

Anti-Calpain LP-82/LP-85 (Lens-Specific Calpain) (Domain III), Large Subunit antibody produced in rabbit has been used in western blotting.

Biochem/physiol Actions

LP82 may regulate calpain activities. It may also play a role in hydrolyzing crystallins during lens cataract formation. LP82 and LP85 along with m-calpain might mediate proteolysis during the typical lens development and maturation or the course of cataract formation in young rodents.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 50% glycerol and 15 mM sodium azide.
