Schematic diagram of the key 3′-UTR elements and RNA binding proteins (RBPs) regulating poly(A) tails in oocytes. The 3′-UTR elements and RBPs mediating polyadenylation and translational activation are shown in red, and the 3′-UTR elements and RBPs mediating deadenylation and translational repression are shown in green. As shown in the dotted box is mitochondria-associated ribonucleoprotein domain associated with several recently discovered functional RBPs.
