Pez: a novel human cDNA encoding protein tyrosine phosphatase- and ezrin-like domains.
We have isolated cDNAs from normal human breast tissue and breast tumour cells that encode a protein (pez) with features of a novel non-receptor tyrosine phosphatase possessing N-terminal sequence homology to the ezrin-band 4.1-merlin-radixin protein family. Northern blot analysis indicates that pez is expressed in a variety of human tissues including kidney, skeletal muscle, lung and placenta. Fluorescence in situ hybridization has mapped pez to chromosome 1 region q32.2-41. Sequence identity to a characterized polymorphic marker confirms this localization.
