Inner centromere protein (INCENP) and centromere protein E (CENPE) are
two functionally important proteins of the higher eukaryotic centrome
re. Using a mouse Incenp genomic DNA and a mouse Cenpe cDNA to analyze
recombinant inbred mouse sets, as well as interspecific backcross pan
els, we have mapped these genes to the proximal regions of mouse Chrom
osomes 19 and 6, respectively. Comparison of Cenpe and human CENPE, wh
ich maps to chromosome region 4q24-->q25, has further identified a new
region of homology between the two species.
