Inhibits mRNA translation in a cytoplasmic polyadenylation element (CPE)-dependent manner. Interacts with CPEB1 and EIF4E. Translocated from nucleolus to nuclear foci in response to UV damage (By similarity). Detected in axons, dendrites and filopodia. Colocalized with EIF4E in neurites. Expressed in testis, ovary, spleen, kidney, hippocampus and cerebellum (at protein level). Expressed in testis, ovary, spleen, kidney, brain. Belongs to the SAS10 family.
