Western blot - Anti-Calpain 2 antibody [EPR2562Y] - BSA and Azide free (AB247423)

This data was developed using the same antibody clone in a different buffer formulation (ab75994).

Lanes 1 - 4 : Merged signal (red and green). Green - ab75994 observed at 75 kDa. Red - loading control ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37 kDa.

ab75994 was shown to react with Calpain 2 in wild-type HEK-293T cells in Western blot with loss of signal observed in CAPN2 knockout cell line ab266628 (CAPN2 knockout cell lysate ab257379). Wild-type HEK-293T and CAPN2 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween^®) before incubation with ab75994 and ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4°C at a 1 in 2000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.

Supplementary information

Calpain 2 also known as CAPN2 or calpain-2 is a heterodimer protease enzyme weighing around 80 kDa. It belongs to the calpain family which requires calcium ions for activation. Calpain 2 expresses in many tissues including the brain muscles and liver indicating its widespread role in cellular processes. The enzyme comprises a large catalytic subunit and a small regulatory subunit each encoded by different genes.

Biological function summary

Calpain-2 plays a significant role in cell signaling cytoskeletal remodeling and apoptosis regulation. It does not typically function in isolation but partners with other molecules forming complexes necessary for precise proteolytic activity. This enzyme modulates several cell functions by cleaving substrates like cytoskeletal proteins transcription factors and enzymes which allows cells to respond adaptively to various stimuli.

Pathways

Calpain-2 integrates into important signaling cascades such as the ERK and PI3K/AKT pathways. It influences these pathways by processing specific proteins and modifying their activity thereby affecting cell survival and proliferation. Calpain-2 closely interacts with proteins like phosphatidylinositol-45-bisphosphate 3-kinase (PI3K) and extracellular signal-regulated kinases (ERKs) within these pathways emphasizing its importance in finely-tuning cellular responses.

Calpain-2 links to several pathological conditions including neurodegenerative diseases like Alzheimer's and muscular disorders such as Duchenne Muscular Dystrophy. In Alzheimer's disease calpain-2 activity influences the processing of amyloid precursor proteins contributing to plaque formation. In Duchenne Muscular Dystrophy calpain-2 activity disrupts muscle fiber integrity through its interaction with proteins like dystrophin aggravating the disorder's progression.

Target data

Calcium-regulated non-lysosomal thiol-protease which catalyzes limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. Proteolytically cleaves MYOC at 'Arg-226' (PubMed : 17650508). Proteolytically cleaves CPEB3 following neuronal stimulation which abolishes CPEB3 translational repressor activity, leading to translation of CPEB3 target mRNAs (By similarity).
