Abstract excerpt

mRNA decapping plays essential roles in regulating gene expression during cellular reprogramming in response to developmental and environmental cues. The evolutionarily conserved PAT1 proteins activate decapping by binding mRNA, recruiting other decapping components, and promoting processing body (PB) assembly. Arabidopsis encodes 3 PAT proteins: PAT1, PATH1, and PATH2. Here, we report that only pat1 mutants...
