Assignment of the vascular smooth muscle actin gene ACTSA to human chromosome 10

Abstract

Human vascular smooth muscle actin gene (ACTSA) was cloned and its unique sequence was used as the hybridization probe for Southern blot analysis of DNAs from 18 rodent-human somatic cell hybrids; the gene was assigned to human chromosome 10. Regional mapping by in situ hybridization showed that the gene is located on the long arm (q22-q24) of the chromosome. Thus, the gene is on a different chromosome from the other four actin genes so far examined. © 1990 The Japan Society of Human Genetics.
