Résumé
A yeast artificial chromosome containing the two receptor-type tyrosine kinase genes FLT1 and FLT3 was isolated, analyzed, and compared to a genomic map in order to establish their organization and linkage. FLT1 and FLT3 are physically linked in a head-to-tail configuration and separated by about 150 kb. The region contains three CpG islands. Two of them are likely to correspond to FLT1 and FLT3, whereas the third one is suggestive of another putative, unidentified RTK gene.
