+== Function ==
+[https://www.uniprot.org/uniprot/THOC4_MOUSE THOC4_MOUSE] Component of the THO subcomplex of the TREX complex. The TREX complex specifically associates with spliced mRNA and not with unspliced pre-mRNA. It is recruited to spliced mRNAs by a transcription-independent mechanism. Binds to mRNA upstream of the exon-junction complex (EJC) and is recruited in a splicing- and cap-dependent manner to a region near the 5' end of the mRNA where it functions in mRNA export. The recruitment occurs via an interaction between ALYREF/THOC4 and the cap-binding protein NCBP1. DDX39B functions as a bridge between ALYREF/THOC4 and the THO complex (By similarity).<ref>PMID:9119228</ref> <ref>PMID:10786854</ref>   Component of a splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junction on mRNAs. The EJC is a dynamic structure consisting of a few core proteins and several more peripheral nuclear and cytoplasmic associated factors that join the complex only transiently either during EJC assembly or during subsequent mRNA metabolism. Plays a role in mRNA processing and export. Acts as chaperone and promotes the dimerization of transcription factors containing basic leucine zipper (bZIP) domains and thereby promotes transcriptional activation. May function as scaffold that mediates interactions between proteins and/or RNA. Integral part of the THO/TREX complex that is recruited to transcribed genes and travels with the RNA polymerase during elongation. Is part of the exon junction complex that remains associated with spliced mRNA and plays an important role in mRNA export and nonsense-mediated RNA decay (By similarity).<ref>PMID:9119228</ref> <ref>PMID:10786854</ref>

+== Publication Abstract from PubMed ==
+ALY is a ubiquitously expressed nuclear protein which interacts with proteins such as TAP that are involved in export of mRNA from the nucleus to the cytoplasm, as well as with proteins that bind the T cell receptor alpha gene enhancer. ALY has also been shown to bind mRNA and to co-localize in the nucleus with components of a multiprotein postsplicing complex that is deposited 20-24 nucleotides upstream of exon-exon junctions. ALY has a conserved RNA binding domain (RBD) flanked by Gly-Arg rich N-terminal and C-terminal sequences. We determined the solution structure of the RBD homology region in ALY by nuclear magnetic resonance methods. The RBD motif in ALY has a characteristic beta(1)alpha(1)beta(2)-beta(3)alpha(2)beta(4) fold, consisting of a beta sheet composed of four antiparallel beta strands and two alpha helices that pack on one face of the beta sheet. As in other RBD structures, the beta sheet has an exposed face with hydrophobic and charged residues that could modulate interactions with other molecules. The loop that connects beta strands 2 and 3 is in intermediate motion in the NMR time scale, which is also characteristic of other RBDs. This loop presents side chains close to the exposed surface of the beta sheet and is a primary candidate site for intermolecular interactions. The structure of the conserved RBD of ALY provides insight into the nature of interactions involving this multifunctional protein.
