Calpain-1 and Calpain-2: The Yin and Yang of Synaptic Plasticity and Neurodegeneration [PDF]
Many signaling pathways participate in both synaptic plasticity and neuronal degeneration. While calpains participate in these phenomena, very few studies have evaluated the respective roles of the two major calpain isoforms in the brain, calpain-1 and calpain-2.

Ginsenoside Rg1 alleviates vascular remodeling in hypoxia-induced pulmonary hypertension mice through the calpain-1/STAT3 signaling pathway [PDF]
Background: Hypoxic pulmonary hypertension (HPH) is the main pathological change in vascular remodeling, a complex cardiopulmonary disease caused by hypoxia. Some research results have shown that ginsenoside Rg1 (Rg1) can improve vascular remodeling, but

Sucrose but not arsenic induce hepatic steatosis which correlates with calpain-1 inhibition. [PDF]
Exposure to arsenic or sugary drinks can increase the risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD), although the mechanisms involved and its possible interactions remain unexplored.

Calpain 1 gene expression in liver tissue and the association of novel calpain 1 single-nucleotide polymorphisms (SNPs) with meat quality in Bali cattle. [PDF]
Abstract. Calpain 1 (CAPN1) is an enzyme that influences meat tenderization, and it is involved in post mortem proteolysis. The bovine CAPN1 gene was chosen as a candidate gene for DNA sequencing to identify novel single-nucleotide polymorphisms (SNPs) in exons 8–10 and assess their associations with meat quality in Bali cattle.

Calpain-1 Cleaves Rad21 To Promote Sister Chromatid Separation [PDF]
Defining the mechanisms of chromosomal cohesion and dissolution of the cohesin complex from chromatids is important for understanding the chromosomal missegregation seen in many tumor cells. Here we report the identification of a novel cohesin-resolving protease and describe its role in chromosomal segregation.

Calpain-3 not only proteolyzes calpain-1 and -2 but also is a substrate for calpain-1 and -2
Abstract Calpain is an intracellular cysteine protease that cleaves its specific substrates in a limited region to modulate cellular function. Calpain-1 (C1) and calpain-2 (C2) are ubiquitously expressed in mammalian cells, but calpain-3 (C3) is a skeletal muscle-specific type.

Changes in neurodegeneration-related miRNAs in brains from CAPN1−/− mice
Calpain-1 knock-out (KO) mice exhibit enhanced susceptibility to neurodegeneration due to the lack of the neuroprotective function of calpain-1. Dicer has been shown to play a fundamental role in the biogenesis of most miRNAs.

Quantification and structure-function analysis of calpain-1 and calpain-2 protease subunit interactions. [PDF]
Calpain-1 and calpain-2 are heterodimeric proteases consisting of a common small regulatory subunit CAPNS1 and a large catalytic subunit, CAPN1 or CAPN2, respectively.

Increased aortic calpain-1 activity mediates age-associated angiotensin II signaling of vascular smooth muscle cells. [PDF]
Angiotensin II (Ang II) signaling, including matrix metalloproteinase type II (MMP2) activation, has been linked to an age-associated increase in migration capacity of vascular smooth muscle cells (VSMC), and to other proinflammatory features of arterial

Calpain-1 Cleaves and Activates Caspase-7 [PDF]
Caspase-7 is an executioner caspase that plays a key role in apoptosis, cancer, and a number of neurodegenerative diseases. The mechanism of caspase-7 activation by granzyme B and caspase-3 has been well characterized. However, whether other proteases such as calpains activate or inactivate caspase-7 is not known.
