GN CDC25 OR SPAC24H6.05. OS SCHIZOSACCHAROMYCES POMBE (FISSION YEAST). OC EUKARYOTA; FUNGI; ASCOMYCOTINA; HEMIASCOMYCETES. RN [1] RP SEQUENCE FROM N.A. RC STRAIN=972; RA BARRELL B.G., RAJANDREAM M.A., WALSH S.V.; RL SUBMITTED (SEP-1995) TO EMBL/GENBANK/DDBJ DATA BANKS. RN [2] RP SEQUENCE FROM N.A. RX MEDLINE; 86161690. RA RUSSELL P., NURSE P.; RL CELL 45:145-153(1986). CC -!- FUNCTION: THIS PROTEIN FUNCTIONS AS A DOSAGE-DEPENDENT INDUCER IN CC MITOTIC CONTROL. IT IS A TYROSINE PROTEIN PHOSPHATASE REQUIRED FOR CC PROGRESSION OF THE CELL CYCLE. IT MAY DIRECTLY DEPHOSPHORYLATE CC P34(CDC2) AND ACTIVATE THE P34(CDC2) KINASE ACTIVITY. CC -!- CATALYTIC ACTIVITY: PROTEIN TYROSINE PHOSPHATE + H(2)O = CC PROTEIN TYROSINE + ORTHOPHOSPHATE. CC -!- SIMILARITY: STRONG, TO OTHER SPECIES M-PHASE INDUCER PHOSPHATASE CC AND IN GENERAL TO PROTEIN-TYROSINE PHOSPHATASES. CC -!- CAUTION: REF.2 SEQUENCE DIFFERS FROM THAT SHOWN FROM POSITION 571 CC ONWARD AND IS SHORTER (580 AA) DUE TO A FRAMESHIFT.
