Sequence-specific RNA-binding protein that acts as a post-transcriptional repressor by binding the 3-UTR of mRNA targets. Binds to an RNA consensus sequence, the Pumilio Response Element (PRE), 5-UGUANAUA-3, that is related to the Nanos Response Element (NRE).Mediates post-transcriptional repression of transcripts via different mechanisms: acts via direct recruitment of the CCR4-POP2-NOT deadenylase leading to translational inhibition and mRNA degradation.
