Kawamukai, M., Ferguson, K., Wigler, M. H., Young, D. (February 1991) Genetic and biochemical analysis of the adenylyl cyclase of Schizosaccharomyces pombe. Cell Regulation, 2 (2). pp. 155-64. ISSN 1044-2030



The adenylyl cyclase gene, cyr1, of Schizosaccharomyces pombe has been cloned. We have begun an analysis of the function and regulation of adenylyl cyclase by disrupting this gene and by over-expressing all or parts of this gene in various strains. cyr1- strains are viable and contain no measurable cyclic AMP. They conjugate and sporulate under conditions that normally inhibit wild-type strains. Strains containing the cyr1 coding sequences transcribed from the strong adh1 promoter contain greatly elevated adenylyl cyclase activity, as measured in vitro, but only modestly elevated cAMP levels. Such strains conjugate and sporulate less frequently than wild-type cells upon nutrient limitation. Strains which carry the wild-type cyr1 gene but that also express high levels of the amino terminal domain of adenylyl cyclase behave much like cyr1-strains, suggesting that the amino terminal domain can bind a positive regulator. A protein that copurifies with the adenylyl cyclase of S. pombe cross-reacts to antiserum raised against the S. cerevisiae adenylyl cyclase-associated regulatory protein, CAP.
