Kallikrein 7 Protein (recombinant mouse)

Activity: Measured by its ability to cleave the fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2 (AnaSpec, Cat#27114).The specific activity is >70 pmoles/min/µg.(Activation description: The proenzyme needs to be activated by Thermolysin for an activated form) Protein Construction: Recombinant Mouse Kallikrein 7 is produced by our Mammalian expression system and the target gene encoding Gln22-Arg249 is expressed with a 6His tag at the C-terminus. Sequence: Met1-Arg249. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 28-35 kDa. Protein function: Kallikrein7, also named as stratum corneum chymotryptic enzyme (SCCE), is a secreted protein of the Kallikrein-related peptidase (KLK) family. This family contains fifteen homologous secreted serine endopeptidases and plays a significant role in various physiological processes, including skin desquamation, semen liquefaction, neural plasticity, and body fluid homeostasis. In skin KLK5, KLK 7 and KLK14 are able to degrade corneodesmosomes, which leads to desquamation of skin surface cells. KLK activation is believed to be mediated through highly organized proteolytic cascades, regulated through a series of feedback loops, inhibitors, auto-degradation and internal cleavages. Studies have shown that one potential physiological activator for KLK7 is KLK5. Along with KLK14, these three kallikreins form a proteolytic cascade in the stratum corneum. KLK7 is primarily expressed in the skin but is also detected at relatively high levels in esophagus, heart, liver, central nervous system, kidney, pancreas, mammary and Protein function: May catalyze the degradation of intercellular cohesive structures in the cornified layer of the skin in the continuous shedding of cells from the skin surface. Specific for amino acid residues with aromatic side chains in the P1 position. Cleaves insulin A chain at '14-Tyr-, -Gln-15' and insulin B chain at '6- Leu-, -Cys-7', '16-Tyr-, -Leu-17', '25-Phe-, -Tyr-26' and '26-Tyr-, - Thr-27'. Could play a role in the activation of precursors to inflammatory cytokines. [The UniProt Consortium]
