Protein phosphorylation plays a crucial role in the regulation of a wi
de array of proteins involved in many cellular processes. Protein phos
phatase 5 (PP5) is a novel member of the protein serine/threonine phos
phatase family. The majority of the cDNA sequence of PP5 has been repo
rted recently. In our study, a sequence encoding the whole open readin
g frame of PP5 was cloned from a human fetal brain cDNA library. The p
rotein phosphatase cDNA sequence of our clone is longer at the 5' end
than the recently published sequence. It's likely that the extended se
quence contains the start codon ATG, since a translation stop codon TA
G is present upstream of the ATG codon in the same open reading frame.
The mRNA of the PP5 gene was detected in all the human tissues examin
ed. The PP5 gene was localized to human chromosomal region 19q13.3. (C
