μ-calpain binds to lipid bilayers via the exposed hydrophobic surface of its Ca2+-activated conformation [PDF]

open access: yes, 2006
μ- and m-calpain are cysteine proteases requiring micro- and millimolar Ca2+ concentrations for their activation in vitro. Among other mechanisms, interaction of calpains with membrane phospholipids has been proposed to facilitate their activation by ...

The calpastatin-derived calpain inhibitor CP1B reduces mRNA expression of matrix metalloproteinase-2 and-9 and invasion by leukemic THP-1 cells [PDF]

open access: yes, 2003
The ubiquitous proteases μ- and m-calpain are Ca2+-dependent cysteine endopeptidases. Besides involvement in a variety of physio(patho)logical processes, recent studies suggest a pivotal role of calpains in differentiation of hematopoietic cells and ...

Characterization of mitochondrial calpain-5 [PDF]

open access: yes, 2022
Calpain, a Ca2+-dependent cysteine protease, plays a significant role in gene expression, signal transduction, and apoptosis. Mutations in human calpain-5 cause autosomal dominant neovascular inflammatory vitreoretinopathy and the inhibition of calpain-5

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 ...

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.

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 ...

Characterisation and expression of calpain family members in relation to nutritional status, diet composition and flesh texture in gilthead sea bream (Sparus aurata). [PDF]

open access: yes, 2013
Calpains are non-lysosomal calcium-activated neutral proteases involved in a wide range of cellular processes including muscle proteolysis linked to post-mortem flesh softening.

Calpain Activity Is Generally Elevated during Transformation but Has Oncogene-Specific Biological Functions

open access: yesNeoplasia: An International Journal for Oncology Research, 2004
Several oncogene and tumor-suppressor gene products are known substrates for the calpain family of cysteine proteases, and calpain is required for transformation by v-src and tumor invasion.
