Predicted to enable mRNA 3'-UTR binding activity; protein dimerization activity; and translation regulator activity. Predicted to be involved in several processes, including positive regulation of response to DNA damage stimulus; regulation of filopodium assembly; and regulation of gene expression. Predicted to be located in several cellular components, including dendrite; glutamatergic synapse; and postsynapse. Predicted to be part of polysome. Predicted to be active in several cellular components, including dendrite; growth cone; and postsynaptic density. Orthologous to human FXR2 (FMR1 autosomal homolog 2).
