Acts as a translational repressor of SRE-containing messengers.
Subcellular locations: Cytoplasm, Cell projection, Dendrite, Synapse, Synaptosome
Enriched in synaptoneurosomes (By similarity). Shuttles between the nucleus and the cytoplasm in a CRM1-dependent manner. Colocalizes throughout the cytoplasm in granules with polyadenylated RNAs, PABPC1 and STAU1. Also frequently colocalizes in cytoplasmic stress granule-like foci with ELAVL1, TIA1 and TIAL1.
