Autogenous proteolytic enzymes of the calpain family are implicated in myofibrillar protein degradation. As a result, the μ-calpain gene and its specific inhibitor, calpastatin, have been repeatedly investigated for their association with meat quality traits in cattle; however, no functional mutation has been identified for these two genes. The objectives of this study were: (1) to assess breed...
calpastatin has been introduced as an effective candidate gene as regards growth efficiency and meat quality traits. throughout the present study, blood sampling as well as carcass trait measurements were performed on 74 lori-bakhtiari sheep and on 40 zel-atabay cross-breds from industrial slaughterhouses of shahrekord and gorgan cities, respectively. following dna extaction, polymerase chain r...
To address the involvement of the calpain system in both basal and silica-induced nuclear factor (NF)-kappaB activation, several human bronchial epithelial cell lines were established in which an intracellular inhibitor of calpain, calpastatin, was stably expressed. Reduced basal and silica-induced inhibitor (IkappaBalpha) degradation and NF-kappaB activation were observed in cells stably overe...
We isolated three Xenopus cDNA clones, Xcalp1, Xcalp2 and Xcalp3, which encode different forms of calpastatin mRNA. Compared to the canonical form of mammalian calpastatin, the predicted Xcalp3 protein contained a very long N-terminal domain L and an additional inhibitory domain. The other two deduced calpastatin proteins were truncated forms, both lacking domain L and containing four (Xcalp2) ...
The objectives of this experiment were to assess effects of animal age and castration on activities of calpain I, calpain II, and calpastatin in sheep skeletal muscle. Ten newborn male lambs (2.9 kg), six weaned wethers (23.2 kg), six weaned rams (22.2 kg), six market wethers (55.4 kg), and six market rams (60.2 kg) were slaughtered and samples of biceps femoris were taken for assay of calpain ...
the genotypes for beta-lactoglobulin (blg) and calpastatin (cast) were determined by polymerase chain reaction (pcr) and restriction enzyme digestion and genotyped for calpain (capn) by pcr-sscp method in a native iranian breed sheep, kordi. blood samples were collected from 100 pure bred kordi sheep from kordi breeding station located in shirvan, mashhad. the extraction of genomic dna was base...
The calpains are a family of intracellular cysteine proteases that function in a variety of important cellular functions, including cell signalling, motility, apoptosis and survival. In early invasive breast cancer expression of calpain-1, calpain-2 and their inhibitor, calpastatin, have been associated with clinical outcome and clinicopathological factors.The expression of calpain-1, calpain-2...
Calpastatin is a widely distributed endogenous inhibitor protein specifically acting on calpain (Ca(2+)-dependent proteinase) and is known to interact with the calmodulin-like domain (CaMLD) of the proteinase in a Ca(2+)-dependent fashion. The calpastatin molecule consists of four inhibitory domains (domains 1-4) with mutually homologous sequences in three regions designated as A, B, and C. Aci...
Restenosis limits the efficacy of vascular percutaneous intervention, in which vascular smooth muscle cell (VSMC) proliferation and activation of inflammation are two primary causal factors. Calpains influence VSMC proliferation and collagen synthesis. However, the roles of calpastatin and calpains in vascular restenosis remain unclear. Here, restenosis was induced by ligating the left carotid ...
Using both in vitro and in vivo approaches, numerous studies have provided evidence that mu-calpain is responsible for postmortem proteolysis. This paper reports the effect of overexpression of calpastatin on postmortem proteolysis in transgenic mice. Transgenic mice (n = 8) with a human calpastatin gene, whose expression was driven by the human skeletal muscle actin promoter, were killed along...
