RNA-binding protein that plays a role in the regulation of transcription, pre-mRNA splicing and mRNA translation. Associates with polysomes. Predominantly cytoplasmic. The C-terminal region is necessary for nucleus and cytoplasmic localization. The N-terminal region is necessary for nucleus and nuclear bodies localization. Able to bind hyaluronan. However, its intracellular localization suggests that this interaction may not be relevant in vivo.
