title: Chromosomal distribution of genes coding for fast twitch skeletal muscle myosin light chains.
abstract: The mouse fast twitch skeletal muscle myosin light chains are encoded by a multigene family which comprises the gene coding for the myosin light chain 2 (Myl2f), and the gene coding for both myosin light chains 1 and 3 (Myl1f/Myl3f). In addition, a Myl1f/Myl3f-related pseudogene is present in the domestic mouse Mus musculus. The members of this gene family were assigned to chromosomes by molecular hybridization, using DNA extracted from a panel of cloned mouse-Chinese hamster somatic hybrid cells and specific DNA probes. The genes coding for the light chains of the myosin molecule are dispersed on several chromosomes, while genes coding for the heavy chain of myosin are located on a single, different chromosome.
