  • Chalone Rangers: The Tissue-Specific Mitotic Inhibitors You Never Knew You Needed

    Chalones are the unsung heroes of cellular crowd control. These tissue-specific, water-soluble substances are like the bouncers of your body, standing at the gates of mitosis with their arms crossed, saying, “Not tonight, buddy.” They’re the biochemical equivalent of that one friend who knows when to call it a night before things get out of…

  • Osteopontin (OPN)

    Osteopontin (OPN), also known as bone /sialoprotein I (BSP-1 or BNSP), early T-lymphocyte activation (ETA-1), secreted phosphoprotein 1 (SPP1), 2ar and Rickettsia resistance (Ric), is a protein that in humans is encoded by the SPP1 gene (secreted phosphoprotein 1). The murine ortholog is Spp1. Osteopontin is a SIBLING (glycoprotein) that was first identified in 1986 in osteoblasts. The family of non-collagenous proteins known as SIBLING proteins, standing for small integrin-binding ligand, N-linked glycoprotein, are components of the extracellular matrix of bone and dentin. Evidence shows that these proteins play key…

  • Carboxypeptidases function in blood clotting, growth factor production, wound healing, reproduction, and many other processes

    A carboxypeptidase (EC number 3.4.16 – 3.4.18) is a protease enzyme that hydrolyzes (cleaves) a peptide bond at the carboxy-terminal (C-terminal) end of a protein or peptide. This is in contrast to an aminopeptidases, which cleave peptide bonds at the N-terminus of proteins. Humans, animals, bacteria and plants contain several types of carboxypeptidases that have diverse functions ranging from catabolism to protein maturation. At least two mechanisms have been discussed. Functions Initial studies…
