설명

일반 설명

A 27-amino acid, cell-permeable peptide encoded by exon 1B of human calpastatin that acts as a potent inhibitor of calpain I and calpain II (IC₅₀ = 20 nM for purified rabbit calpain II). Does not inhibit either papain or trypsin. Blocks the down-regulation of protein kinase C_ε (PKC_ε) in rat pituitary GH₄C₁ cells stimulated by thyrotropin-releasing hormone (TRH).
