Summary: | A detailed functional and evolutionary analysis of an enhancer element of the human genome (enhancer 12) located in the second intron of the
U2AF1L4
gene, which we identified earlier, is presented. Overlapping fragments of the studied genome region were analyzed for enhancer activity, and the site responsible for the activity of this element was identified using transient transfections of HeLa cells. Comparison of the enhancer 12 sequence with orthologous sequences from seven primate species revealed the existence of evolutionarily conserved sequences within this element. One of the identified conservative regions is likely responsible for the enhancer activity and is able to specifically interact
in vitro
with proteins of HeLa cell nuclear extract. The ability of orthologous primate sequences to compete with enhancer 12 for binding with HeLa cell nuclear extract proteins and to enhance the activity of the reporter gene in transient transfection of HeLa cells is demonstrated. |
