U. Iowa team investigates function of 'junk DNA' in human genes
Date:2/28/2011

ed because of which genes were "targeted" by the Alu exons. The researchers found that Alu exons are highly enriched in genes that code for zinc-finger transcription factors -- proteins that act as master regulators of gene expression and that previously have been linked to human and primate evolution. Because these transcription factors control the expression of thousands of other genes, any changes to the amount of transcription factor available would likely have a cascade effect on the downstream genes.
