The organization and conservation of the human Surfeit gene cluster and its localization telomeric to the c-abl and can proto-oncogenes at chromosome band 9q34.1.
The mouse Surfeit locus contains an unusually tight cluster of six housekeeping genes (Surf-1 to -6) which are unrelated by sequence homology. Using a mouse Surfeit locus probe, a 16 kb clone has been isolated which contains the human Surf-1 and Surf-3 genes and regions of the human Surf-2 and Surf-5 genes. The organization and juxtaposition of these human Surfeit locus genes are the same as found in the mouse. Using the human clone as a biotinylated probe for fluorescence in situ hybridization (FISH) we have confirmed the location of the human Surfeit locus to chromosome band 9q34. Metaphase spreads of human chronic myeloid leukemic cells containing the t(9;22)(q34;q11) translocation involving The c-abl gene at 9q34.1 an acute nonlymphocytic leukemic cells containing the t(6;9)(q34;p23) translocation involving the can gene at 9q34.1 were analyzed by FISH using the human Surfeit clone as a probe. These analyses locate the human Surfeit locus telomeric to the c-abl and can genes at chromosome band 9q34.1.
