Assignment of the genes for triose phosphate isomerase to chromosome 6 and tripeptidase-1 to chromosome 10 in Mus musculus by somatic cell hybridization

Evidence is presented for the assignment of the gene for triose phosphate isomerase to Mus musculus chromosome 6 and tripeptidase-1 to chromosome 10 by synteny testing and chromosome assignment in Chinese hamster X mouse somatic cell hybrid clones. Neither TPI nor TRIP-1 were expressed concordantly with any known isozyme markers in 45 hybrid clones (13 primary and 32 secondary). Karyotypic analysis of 21 clones showed that the expression of TPI and chromosome 6 were concordant in all cases as was expressed of TRIP-1 and chromosome 10. Both chromosomes were previously unmarked by isozymes.
