CC   -!- FUNCTION: Multifunctional polyribosome-associated RNA-binding protein
CC       that plays a central role in neuronal development and synaptic
CC       plasticity through the regulation of alternative mRNA splicing, mRNA
CC       stability, mRNA dendritic transport and postsynaptic local protein
CC       synthesis of a subset of mRNAs (By similarity). Binds poly(G) and
CC       poly(U), and to a lower extent poly(A) and poly(C).

CC   -!- TISSUE SPECIFICITY: During early to late tailbud stage, expression
CC       intensifies in the craniofacial region with prominent staining in the
CC       endodermal, mesodermal and mesenchymal regions of the pharyngeal
CC       arches. By early tadpole stage (stage 35), expressed in the forebrain,
CC       midbrain, hindbrain and notochord in addition to craniofacial regions
CC       including the ear vesicles and eye. In the central nervous system (CNS)
CC       of late tadpoles (stage 45), expressed in the olfactory bulbs and the
CC       cerebellum. In adults, expressed predominantly in the brain.
CC       {ECO:0000269|PubMed:16000371, ECO:0000269|PubMed:16281176}.
CC   -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically. Zygotic
CC       expression begins just prior to gastrulation (stage 10) and gradually
CC       increases during subsequent embryonic stages.
CC       {ECO:0000269|PubMed:16281176}.
CC   -!- SIMILARITY: Belongs to the FMR1 family. {ECO:0000305}.
