Calpain 2,

calpain 2, m-Calpain, CAPN2, mCANP
The 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009] (from NCBI)

Airway epithelial dual oxidase 1 mediates allergen-induced IL-33 secretion and activation of type 2 immune responses.
New
van der Vliet et al., Budapest, Hungary. In J Allergy Clin Immunol, Dec 2015
RESULTS: In vitro or in vivo allergen challenge resulted in rapid airway epithelial IL-33 secretion, which depended critically on DUOX1-mediated activation of epithelial epidermal growth factor receptor and the protease calpain-2 through a redox-dependent mechanism involving cysteine oxidation within epidermal growth factor receptor and the tyrosine kinase Src.
LOX-1 in macrophage migration in response to ox-LDL and the involvement of calpains.
New
Mehta et al., Xinxiang, China. In Biochem Biophys Res Commun, Dec 2015
Our results showed that ox-LDL stimulated LOX-1 and calpain-2 expression, and inhibited calpain-1 expression in a dose- and time-dependent manner.
Calpain Cleaves Most Components in the Multiple Aminoacyl-tRNA Synthetase Complex and Affects Their Functions.

New
Kim et al., Dover, United States. In Brain Res, Nov 2015
Mechanistically, lithium was found to suppress MPTP-induced calpain activities in vivo coinciding with down-regulation of calpain-1 but not calpain-2 expression in both the striatum (ST) and the brain stem (BS).
Calpain Determines the Propensity of Adult Hippocampal Neural Stem Cells to Autophagic Cell Death Following Insulin Withdrawal.
New
Yu et al., Taegu, South Korea. In Stem Cells, Oct 2015
Our results indicate that low calpain activity, due to absence of calpain 1 and degradation of calpain 2, results in a preference for ACD over apoptosis in insulin-deprived HCN cells.

New
Su et al., Augusta, United States. In Am J Respir Cell Mol Biol, Sep 2015
The calcium chelator BAPTA/AM did not affect calpain activation but the extracellular signal-regulated kinase 1/2 (ERK1/2) inhibitor PD98059 and knocking down of calpain-2 prevented calpain activation in PAH mediator-treated PASMCs.

Melloni et al., Genova, Italy. In Plos One, 2014
We have recently demonstrated that in resting conditions calpain 1, but not calpain 2, is specifically associated to the N-Methyl-D-Aspartate receptor (NMDAR) multiprotein complex.
