title: The ras-related ral gene maps to chromosome 7p15-22.
abstract: Human cDNAs coding for the new protein ral that shares 50% homology with the ras proteins have been recently isolated. A 600-bp fragment carrying mainly the coding region was used to localize the ral gene by hybridization with sorted chromosomes and in situ hybridization. Direct molecular hybridization on sorted chromosomes using a single laser illumination allowed the assignment of the ral gene to a region of the flow karyotype containing chromosomes 7, 8 and X. With dual laser analysis ral was assigned to the fraction containing chromosome 7. In the 331 human metaphases hybridized with the 3H-labelled insert, the silver grain distribution showed a unique major signal on chromosome 7p15-22.
