The abundant homohexameric AAA + ATPase p97 (also known as valosin-containing protein, VCP) is highly conserved from Dictyostelium discoideum to human and a pivotal factor of cellular protein homeostasis it catalyzes the unfolding proteins. Owing its fundamental function in quality control pathways, regulated by more than 30 cofactors, including UBXD family, whose members all carry an Ubiquitin...

Calpastatin is an endogenous inhibitor of calpain (calcium-dependent cysteine protease). Calpastatin activityis highly related to the rate of protein turnover and rate of meat tenderization. In order to characterize thestructure of calpastatin in Iranian Afshari breed of sheep, intron 6 and partial exon 7 of the L domain wereamplified and sequenced. A fragment of approximately...

the present study was aimed to construct a fusion plasmid harboring the extracellular domain of the influenza a m2-protein (m2e), which was fused to the n-terminus of the truncated hsp70 (hsp70359–610) molecule as a new approach for future vaccine research against influenza a. the amplified fragments, m2e and hsp70359-610 genes, were gel-purified. the products were then single digested with bam...
