Human μ-calpain: Simple isolation from erythrocytes and characterization of autolysis fragments [PDF]

open access: yes, 2001
Heterodimeric μ-calpain, consisting of the large (80 kDa) and the small (30 kDa) subunit, was isolated and purified from human erythrocytes by a highly reproducible four-step purification procedure.

GPS-CCD: a novel computational program for the prediction of calpain cleavage sites. [PDF]

open access: yesPLoS ONE, 2011
As one of the most essential post-translational modifications (PTMs) of proteins, proteolysis, especially calpain-mediated cleavage, plays an important role in many biological processes, including cell death/apoptosis, cytoskeletal remodeling, and the ...

Augmented generation of protein fragments during wakefulness as the molecular cause of sleep: A hypothesis [PDF]

open access: yes, 2012
Despite extensive understanding of sleep regulation, the molecular-level cause and function of sleep are unknown. I suggest that they originate in individual neurons and stem from increased production of protein fragments during wakefulness.

An eccentric calpain, CAPN3/p94/calpain-3

open access: yesBiochimie, 2016
Calpains are Ca(2+)-regulated proteolytic enzymes that are involved in a variety of biological phenomena. Calpains process substrates by limited proteolysis to modulate various protein functions in the cell, and are thus called "modulator proteases." CAPN3, previously called p94 or calpain-3, has unique features that are not found in any of the other ...

Calpain activity is negatively regulated by a KCTD7–Cullin-3 complex via non-degradative ubiquitination

open access: yesCell Discovery, 2023
Calpains are a class of non-lysosomal cysteine proteases that exert their regulatory functions via limited proteolysis of their substrates. Similar to the lysosomal and proteasomal systems, calpain dysregulation is implicated in the pathogenesis of ...

Activation of calpain-1 in human carotid artery atherosclerotic lesions

open access: yesBMC Cardiovascular Disorders, 2009
Background In a previous study, we observed that oxidized low-density lipoprotein-induced death of endothelial cells was calpain-1-dependent. The purpose of the present paper was to study the possible activation of calpain in human carotid plaques, and ...

Inhibition of calpain prevents manganese-induced cell injury and alpha-synuclein oligomerization in organotypic brain slice cultures. [PDF]

open access: yesPLoS ONE, 2015
Overexposure to manganese has been known to promote alpha-synuclein oligomerization and enhance cellular toxicity. However, the exact mechanism of Mn-induced alpha-synuclein oligomerization is unclear.

Reduction of myocardial infarction by postischemic administration of the calpain inhibitor A-705253 in comparison to the Na(+)/H(+) exchange inhibitor Cariporide (R) in isolated perfused rabbit hearts [PDF]

open access: yes, 2008
The calpain inhibitor A-705253 and the Na(+)/H(+) exchange inhibitor Cariporide (R) were studied in isolated perfused rabbit hearts subjected to 60 min occlusion of the ramus interventricularis of the left coronary artery (below the origin of the first ...
