Anti-proliferative protein; the function is mediated by association with deadenylase subunits of the CCR4-NOT complex (, ). Mediates CPEB3-accelerated mRNA deadenylation by binding to CPEB3 and recruiting CNOT7 which leads to target mRNA deadenylation and decay .
Subcellular locations: Cytoplasm, Nucleus
Only a small fraction localizes to the cytoplasm except in late S-phase where more than half of proteins become cytoplasmic.
Ubiquitous.
