Calpains are calcium-modulated proteases which respond to Ca2+ signals by removing limited portions of protein substrates, thereby irreversibly modifying their function(s). Members of this protease family are present in a variety of organisms ranging from mammals to plants; some of them are ubiquitously expressed, while others are tissue specific. Although calpains are apparently involved in a multitude of physiological and pathological events, their functions are still poorly understood. In two cases, however, the alteration of a member of the calpain family has been clearly identified as being responsible for a human disease: the loss of function of calpain 3 causes limb girdle muscular dystrophy type 2A, and mutations in the gene coding for calpain 10 have been shown to correlate with non-insulin-dependent diabetes.

Abstract
Calpains are calcium-modulated proteases which respond to Ca2+ signals by removing limited portions of protein substrates, thereby irreversibly modifying their function(s). Members of this protease family are present in a variety of organisms ranging from mammals to plants; some of them are ubiquitously expressed, while others are tissue specific. Although calpains are apparently involved in a multitude of physiological and pathological events, their functions are still poorly understood. In two cases, however, the alteration of a member of the calpain family has been clearly identified as being responsible for a human disease: the loss of function of calpain 3 causes limb girdle muscular dystrophy type 2A, and mutations in the gene coding for calpain 10 have been shown to correlate with non-insulin-dependent diabetes.Pubblicazioni consigliate
