Expression of the human CL100 gene is induced in skin fibroblasts in response to oxidative/heat stress and growth factors. The CL100 gene encodes a dual specificity (Tyr/Thr) protein phosphatase that specifically inactivates mitogen-activated protein (MAP) kinase in vitro. In addition, CL100 is able to suppress the activation of MAP kinase by oncogenic ras in extracts of Xenopus oocytes. Thus, the CL100 phosphatase may play an important role in the negative regulation of cellular proliferation and is a likely candidate for a tumour-suppressor gene. Here, we show that DNA sequences homologous to CL100 are present in genomic DNA isolated from mouse, chicken, Xenopus and Drosophila, indicating that the CL100 gene is highly conserved. Using an assay based on the polymerase chain reaction, in conjunction with genomic DNA obtained from human-rodent somatic-cell hybrids, we have determined that the CL100 gene is situated on chromosome 5. Fluorescence in situ hybridisation using a CL100 genomic probe confirms that the CL100 mRNA is transcribed from a single genetic locus and maps the gene to 5q34.
