FEBS Lett. 1989 Apr 24;247(2):391-5. Molecular cloning and chromosomal localization of a novel Drosophila protein phosphatase. Dombrádi V, Axton JM, Glover DM, Cohen PT. Department of Biochemistry, University of Dundee, Scotland. Abstract A 1.0 kilobase cDNA coding for the complete amino acid sequence of a putative protein phosphatase (314 amino acid residues, molecular mass 36 kDa) has been isolated from a Drosophila head cDNA library. The cDNA hybridises to a single site on the right arm of the second chromosome at cytological position 55A1-3. The deduced sequence of the protein, designated protein phosphatase-Y, is homologous to the catalytic subunits of Drosophila and rabbit protein phosphatase-1 alpha (64 and 59% identity, respectively) and rabbit protein phosphatase-2A (39% identity). These and other comparisons demonstrate that this novel enzyme is not the Drosophila counterpart of mammalian protein phosphatases 1, 2A, 2B, 2C or X.

A cDNS hibridizál egy oldalt a jobb kar a második kromoszóma a citológiai helyzetben 55A1-3. A levezethető sorrendje a fehérje, kijelölt protein foszfatáz-Y, homológ a katalitikus alegység a Drosophila és a nyúl protein foszfatáz-1 alfa (64 és 59%-identitás-kal) és a nyúl protein foszfatáz-2A (39% identitás). Ezek és más összehasonlítások azt mutatják, hogy ez az új enzim nem a Drosophila megfelelője az emlősökből származó fehérjék foszfatázok 1, 2A, 2B, 2C vagy X.
