A gene encoding a novel member of the PPP family of protein serine/threonine phosphatases, termed PPN 58A, was cloned from Drosophila melanogaster. The deduced amino acid sequence of PPN 58A exhibits 59-62% identity to D. melanogaster PP1 isoforms, 51% identity to D. melanogaster PPY 55A and ≤40% identity to other members of the PPP family. The single copy gene PPN 58A maps to chromosome 2 locus 58A. Analysis of PPN 58A mRNA reveals that, like PPY 55A, PPN 58A is a testis specific enzyme.
