Can ACG serve as an initiation codon for protein synthesis in eucaryotic cells?

abstract：:The imprinted expression of the H19 and Igf2 genes in the mouse is controlled by an imprinting control center (ICR) whose activity is regulated by parent-of-origin differences in methylation. The only protein that has been implicated in ICR function is the zinc-finger protein CTCF, which binds at multiple sites within...
