Physical mapping of receptor type protein tyrosine phosphatase sigma (PTPRS) to human chromosome 19p13.3.

Receptor type protein tyrosine phosphatase sigma (PTPRS), a member of a subfamily of receptor type protein tyrosine phosphatases, has been mapped to human chromosome 19p13.3 using fluorescence in situ hybridization (FISH) analysis. Hybridization analysis of chromosome 19 library cosmids has revealed several positive clones that are part of a contig located in the same region. The location of this contig was verified since one of the cosmid clones is anchored to a high-resolution FISH map of human chromosome 19p. In addition, the location of this gene relative to previously mapped proximal markers reveals a new point in the human-mouse synteny map by extending the mouse chromosome 17 synteny region in the telomeric direction.
