Abstract
MRNA isolated from fetal human aorta was used to synthesize cDNA that was cloned into the PstI site of pBR322. The recombinant clones were screened with an authentic sheep elastin cDNA, and one human clone that hybridized strongly was isolated and characterized. The 421-base pair (bp) inset of this human clone was sequenced by the dideoxy method, and the DNA sequence showed strong homology to the nontranslated portion of the sheep elastin cDNA. This result unequivocally identified the human clone, designated pcHEL1, as an elastin clone. Plasmid pcHEL1 labeled with [3H] nucleotides was used in in situ hybridization experiments utilizing normal metaphase chromosomes and also with cells carrying a balanced translocation between chromosomes 1 and 2: 46,XY,t(1;2)(p36;q31). The results strongly suggest that the elastin gene is localized to the q31 .fwdarw. qter region of chromosome 2.This publication has 40 references indexed in Scilit:
