Dynamins, microtubule-binding GTPases, are encoded by at least three genes in mammals. Two distinct gene-specific cDNAs were used to analyze the segregation of dynamin genes Dnm1 and Dnm2 in a mouse interspecies backcross. The nervous system expressed gene Dnm1 was localized to Chr 2 between the genes for vimentin and nebulin, within a chromosomal region of conserved synteny to human chromosome 9q, consistent with the localization of the human dynamin-1 gene by FISH (see accompanying paper by Newman-Smith et al., 1997, Genomics 41: 286-289). The ubiquitously expressed Dnm2 gene was found to be closely linked to the intercellular adhesion molecule-1 gene, Icam1, in a region with homologies to human chromosomes 19p, 8q, and 11q. Potential relations of both loci to disease genes are discussed. (C) 1997 Academic Press.
