Domaini

The leucine-rich repeats and the NTF2-domain are essential for the export of mRNA from the nucleus.By similarity
The NTF2 domain heterodimerizes with MTR2. The formation of this heterodimer is essential for mRNA export and binds to all of the nucleoporin-FG-repeats.
The RNA-binding domain is conserved in most NXF proteins but may be absent in yeasts.

Sequence similaritiesi

Belongs to the NXF family.Curated
