Yeast has homologs (CNA1 and CNA2 gene products) of mammalian calcineurin, a calmodulin-regulated phosphoprotein phosphatase
Open accessAbstract
Calcineurin, or phosphoprotein phosphatase type 2B (PP2B), is a calmodulin-regulated phosphoprotein phosphatase. We isolated a gene encoding a yeast PP2B homolog (CNA1) by screening a yeast genomic DNA library in the expression vector lambda gt11, first with 125I-labeled yeast calmodulin and then with a human cDNA encoding the catalytic (or A) subunit of calcineurin. The predicted CNA1 gene product is 54% identical to its mammalian counterpart. Using the polymerase chain reaction (PCR) with oligonucleotide primers based on sequences conserved between CNA1 and mammalian PP2B genes, we isolated a second gene, CNA2. CNA2 is identical to PP2Bw, a partial cDNA clone previously described by others as originating from rabbit brain tissue. Our findings demonstrate that a unicellular eukaryote contains phosphoprotein phosphatases of the 2B class. Haploid cells containing a single cna1 or cna2 null mutation, or both mutations, were viable. MATa cna1 cna2 double mutants were more sensitive than wild-type cells or either single mutant to growth arrest induced by the mating pheromone alpha factor and failed to resume growth during continuous exposure to alpha factor. Thus, calcineurin action antagonizes the mating-pheromone response pathway.

Calcineurin is required in S. cerevisiae and S. pombe for adaptation to environmental stresses, cation homeostasis, morphogenesis, cell wall integrity, and mating.
“Calcineurin has been well characterized in the model yeasts S. cerevisiae and Schizosaccharomyces pombe, where it is required for adaptation to a variety of environmental stresses, cation homeostasis, morphogenesis, cell wall integrity, and mating (Cyert et al., 1991; Matsumoto et al., 2002; Mendoza et al., 1996; Mendoza et al., 1994; Sugiura et al., 2002).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
