| pubmed-article:8294211 | pubmed:abstractText | Protein tyrosine phosphatase (PTP) negatively regulates the effect of protein tyrosine kinases and is implicated in the regulation of a variety of biological phenomena such as cell activation, differentiation and neoplastic transformation. To gain insight into the role of PTPs, we cloned the human receptor-type PTP gene and assigned the chromosome harboring the gene for HPTP delta by using DNAs from human-mouse hybrid cell lines and by fluorescence in situ hybridization. The results clearly demonstrated that HPTP delta gene maps to human chromosome 9p24. | lld:pubmed |
