Description Developmental regulation of elastin synthesis occurs through modulation of the stability of its mRNA. It has been demonstrated that the binding of cytosolic proteins to a large region of the 3'UTR of elastin mRNA, possibly folded into a stable secondary structure, is associated to stabilization/destabilization of elastin mRNA. Using deletion and competition analyses the core cis-acting sequence has been mapped to a 20 nt long purine rich sequence containing at least a 3-fold repeat of GGGA (G3A) motif conserved from human to chicken.
