Post-translational processing of gastrin in neoplastic human colonic tissues.
Gastrin has been postulated to stimulate proliferation in colorectal neoplasms. Although gastrin mRNA has been demonstrated to be present in colon cancer cell lines, the intact peptide had not been recovered from human colorectal neoplasms. We demonstrate that gastrin and its precursors are present in both colorectal neoplasia and adjacent normal-appearing colonic mucosa. In colonic tissue, the...
متن کاملPost-translational modification and proteolytic processing of urinary osteopontin.
OPN (osteopontin) is a highly phosphorylated glycoprotein present in many tissues and body fluids. In urine, OPN is a potent inhibitor of nucleation, growth and aggregation of calcium oxalate crystals, suggesting that it has a role in the prevention of renal stone formation. The role of OPN in nephrolithiasis is, however, somewhat unclear, as it may also be involved in urinary stone formation, ...
متن کاملDystrophin-glycoprotein complex: post-translational processing and dystroglycan function.
The dystrophin-glycoprotein complex (DGC) is a multimeric transmembrane protein complex first isolated from skeletal muscle membranes (1). The central protein of the DGC is dystroglycan (Fig. 1). In addition to skeletal muscle, dystroglycan is strongly expressed in heart and smooth muscle, as well as many non-muscle tissues including brain and peripheral nerve. In vertebrates, dystroglycan is g...
متن کاملModifying secretion and post-translational processing in insect cells.
The baculovirus-insect cell system is a valuable tool for the expression of heterologous proteins. Due to limitations in the intracellular processing environment, however, heterologous secreted and membrane proteins are often insoluble, poorly processed, or contain 'non-human' modifications. Recent attempts to modify the insect cell secretory pathway by overexpressing processing factors have de...
متن کاملPost-translational processing targets functionally diverse proteins in Mycoplasma hyopneumoniae.
Mycoplasma hyopneumoniae is a genome-reduced, cell wall-less, bacterial pathogen with a predicted coding capacity of less than 700 proteins and is one of the smallest self-replicating pathogens. The cell surface of M. hyopneumoniae is extensively modified by processing events that target the P97 and P102 adhesin families. Here, we present analyses of the proteome of M. hyopneumoniae-type strain...
