CC -!- FUNCTION: RNA-binding protein that plays a central role in
CC myelinization. Binds to the 5'-NACUAAY-N(1,20)-UAAY-3' RNA core
CC sequence. Acts by regulating pre-mRNA splicing, mRNA export, mRNA
CC stability and protein translation. Required to protect and promote
CC stability of mRNAs which promotes oligodendrocyte differentiation.
CC Participates in mRNA transport by regulating the nuclear export of MBP
CC mRNA. Also involved in regulation of mRNA splicing of some pre-mRNA.
CC Acts as a translational repressor (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. Does not require RNA to homodimerize (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.

CC Name=1;
CC IsoId=Q6P0D0-1; Sequence=Displayed;
CC Name=2; Synonyms=ZD;
CC IsoId=Q6P0D0-2; Sequence=VSP_019204;
CC -!- DEVELOPMENTAL STAGE: Maternally and zygotically expressed. Ubiquitously
CC expressed during cleavage and blastula periods, and then it accumulates
CC in the dorsal midline of the body trunk during gastrulation. During
CC segmentation and pharyngula periods it is expressed in the neural
CC tissue of the head region, and in the paraxial mesoderm of the body
CC trunk. Subsequently expression diminishes until the hatching period,
CC when it is expressed only in the cardiac sac and pectoral finbuds.
CC Isoform 2 localizes in neural tissue in the head region, but not in the
CC paraxial mesoderm in the body trunk. {ECO:0000269|PubMed:9486543}.
