Protein
Insulin-like growth factor 2 mRNA-binding protein 3-A
Function
RNA-binding protein that act as a regulator of mRNA transport and localization. Mediates the specific association of Vg1 RNA to microtubules. Binds specifically to the vegetal localization elements (VLE or VgLE) in the 3'-UTR of Vg1 and VegT mRNAs. Binds to the Vg1 and VegT mRNAs in both the nucleus and the cytoplasm. Binds to the RNA sequence motif 5'-UUCAC-3'. May regulate mRNA translation (By similarity). Acts as a transcription regulator (By similarity). Binds to the 5'-[TA]GGTTACT-3' motif within element 3 of the TFIIIA gene promoter. Binds DNA (By similarity).
Similarity
Belongs to the RRM IMP/VICKZ family.
