Calpain-1 (CAPN1), an intracellular, calcium-dependent cysteine protease, has four domains, such as, the N-terminal anchor helix region, the CysPc protease domain, the C2 domain-like domain and the penta-EF-hand domain (PEF). CAPN1 codes for μ-calpain protein. CAPN1 gene is abundantly expressed in the central nervous system (CNS). This gene is located on human chromosome 11q13.1.
Specificity
Specifically recognizes the 80 kDa subunit of μ-calpain as well as two smaller proteins that are presumed to be degradation products.
Immunogen
purified human μ-calpain from placenta (calpain-I, protein kinase-C activating factor, E.C. 3.4.22.17).
Application
Monoclonal Anti-μ-Calpain (Calpain I, subunit p80) antibody produced in mouse has been used in:
Calpain-1 (CAPN1) plays a key role in microtubular regulation, cerebellar development, synaptic plasticity, synaptic restructuring, axon maturation and maintenance. CAPN1 activation is essential to provide a neuro-protective role in central nervous system (CNS). Mutations on CAPN1 gene results in spastic paraplegia 76 (SPG7), a complicated form of hereditary spastic paraplegia (HSP).
Physical form
Solution in 20 mM sodium phosphate, 150 mM sodium chloride, 50% glycerol, pH 7.5, and 3 mM sodium azide.

To characterize the phenotype of CAPN1 (SPG76) mutations in patients diagnosed with hereditary spastic paraplegia (HSP). The CAPN1 gene, located on chromosome 11q13.1, is a protein-coding gene involved in neuronal plasticity, migration, microtubular regulation and cerebellar development. Several families with

Denervated fast skeletal muscles undergo atrophy, which is associated with an increase in sarcolemma permeability and protein imbalance. However, the mechanisms responsible for these alterations remain largely unknown. Recently, a close association between de novo expression of hemichannels formed by

Hereditary spastic paraplegias (HSP) are of great clinical and genetic heterogeneity. According to the clinical features, HSP can be divided into pure or complicated subtypes which combined with other neurological symptoms including cerebellar ataxia. Up to date, 78 loci or

We are here reporting that in peripheral blood mononuclear cells (PBMC) of patients homozygous for F508del-CFTR the calpain-calpastatin system undergoes a profound alteration. In fact, calpain basal activity, almost undetectable in control PBMC, becomes measurable at a significant extent in
Short-term intermittent hypoxia (IH) is common in patients with acute respiratory disorders. Although prolonged exposure to hypoxia induces atrophy and increased fatigability of skeletal muscle, the response to short-term IH is less well known. We hypothesized that the diaphragm and
