Abstract excerpt
We have recently characterized a mutant insulin receptor (Y/F2) in which the two tyrosines in the carboxyl terminus (Tyr1316, Tyr1322) were mutated to phenylalanine. Compared with wild type receptors, the Y/F2 receptor exhibited markedly enhanced sensitivity to insulin-stimulated DNA synthesis with normal insulin-stimulated glucose uptake (Takata, Y., Webster, N. J. G., and Olefsky, J. M. (1991) J. Biol. Chem....
