The sequence of 55 kb on the left arm of yeast chromosome XVI identifies a small nuclear RNA, a new putative protein kinase and two new putative regulators.
We have sequenced and analysed a 55786 bp fragment located on the left arm of chromosome XVI of Saccharomyces cerevisiae. The sequence contains 29 non-overlapping open reading frames (ORFs) longer than 300 bp, among which 12 genes have previously been sequenced: OYE3, REV3, SVS1, BEM4, CDC60, KIP2, PEP4, SPK1, PAL1, KES1, SNR17B and RPL37A. Three new ORFs, P2591, P2594 and P2597 are highly homologous to the human phosphotyrosyl phosphatase activator PTPA, to the pleiotropic regulator PRL1 of PP1 and PP2a protein phosphatases in plants and to the protein kinase PAR-1 in Caenorhabditis elegans, respectively. Three other ORFs, P2545, P2567 and P2578 have significant homology with ORFs of unknown function located on yeast chromosomes VIII, XVI and IV respectively.
