title: An expressed beta-tubulin gene, TUBB, is located on the short arm of human chromosome 6 and two related sequences are dispersed on chromosomes 8 and 13.
abstract: The chromosomal assignments of an expressed beta-tubulin gene and two related sequences have been determined by Southern blot analysis of DNA from a panel of human x Chinese hamster somatic cell hybrids cleaved with Hind III or EcoRI. Probes containing the 3' untranslated regions of the expressed gene M40 and of pseudogene 21 beta were used to localize the M40 sequence (gene symbol TUBB) to chromosome 6 region 6p21----6pter, the 21 beta pseudogene (TUBBP1) to chromosome 8 region 8q21----8pter and a third related sequence (TUBBP2) to chromosome 13. Asynteny of expressed genes and related processed pseudogenes has now been demonstrated for several gene families.
