Cytoplasmic polyadenylation
WebJul 1, 2013 · Cytoplasmic polyadenylation element binding protein (CPEB)3 is a sequence-specific RNA-binding protein that regulates translation of several PRP RNAs in neurons. WebJun 13, 2007 · CPEB1 binds to a short AU-rich sequence in responsive mRNAs called the cytoplasmic polyadenylation element (CPE) in the 3′ untranslated region (UTR). CPEB1 initially represses the translation of bound mRNA and activates translation after phosphorylation at T 171 and S 177 ( de Moor and Richter, 1999; Mendez et al., 2000b ).
