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.

Fordítás:
A 1,0 kilobase cDNS kódoló a teljes aminosav-szekvenciáját egy feltételezett fehérje
foszfatáz (314 aminosavból, molekulatömege 36 kDa) izolálták a Drosophila cDNS könyvtár
vezetője. 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.
