WebCHIP28 is a 28-kD hydrophobic integral membrane protein that functions as a water channel in erythrocytes and renal tubule epithelial cell membranes. We examined the … WebJan 15, 1993 · CHIP28 is a 28-kD integral protein which was proposed to mediate transmembrane water movement in red cells and kidney (Preston, G. M., T. P. Carroll, W. B. Guggino, and P. Agre. 1992. Science [Wash. DC]. 256:385-387). To determine whether CHIP28 could account for renal epithelial water transport, we used specific polyclonal …

WebThe coinjection of an antisense oligonucleotide for CHIP28 protein, at an assumed > 100-fold molar excess, with either cortex, medulla, or papilla mRNA reduced the expression of the water permeability by approximately 70, 100, and 30%, respectively. Exposure of the oocyte to cAMP for 1 h resulted in a further increase in Pf only in oocytes ... WebFor urea, Goldstein and Solomon (1960) found that sigma urea = 0.62 +/- 0.03 which meant that urea crosses the red cell membrane in a water-filled channel. This result and many subsequent observations that showed that sigma urea < 1.0 are at variance with the observation that CHIP28 is impermeable to urea. In view of this problem, we have made ... raytown south basketball

WebDec 15, 1991 · CHIP28 is a 28-kDa integral membrane protein with similarities to membrane channels and is found in erythrocytes and renal tubules. A cDNA for CHIP28 was isolated from human fetal liver cDNA template by a three-step polymerase chain reaction (PCR) cloning strategy, starting with degenerate oligonucleotide primers corresponding to the N … WebJan 5, 1993 · These studies demonstrated: (i) CHIP28 water channel activity is retained despite substitution of individual cysteines with serine; (ii) cysteine 189 is the Hg (2+)-sensitive residue; (iii) the subunits of the CHIP28 complex are individually active water pores; (iv) residue 189 is critical to proper processing of the CHIP28 protein.
