pfam12066: SERRATE_Ars2_N (This model is not part of the current CDD release)
SERRATE/Ars2, N-terminal domain
This domain can be found in the N terminus of the SERRATE (SE) from plants and its homologue, Ars2, from animals. They play a role in nuclear RNA metabolism. They interact with the nuclear cap-binding complex (CBC) and mediates interactions with diverse RNA processing and transport machineries in a transcript-dependent manner. Interestingly, the plant SERRATE does not have the RNA recognition motif (RRM) domain found in metazoans and S. pombe. This domain has two completely conserved Y residues that may be functionally important.
