Also known as ALYBEFALY/REFREF
Summary
ALYREF (Aly/REF export factor, HGNC:19071) is a protein-coding gene on chromosome 17q25.3, encoding THO complex subunit 4 (Q86V81). Functions as an mRNA export adapter; component of the transcription/export (TREX) complex which is thought to couple mRNA transcription, processing and nuclear export, and specifically associates with spliced mRNA and not with unspliced pre-mRNA. It is a common-essential gene (DepMap: required in 98.1% of cancer cell lines).
The protein encoded by this gene is a heat stable, nuclear protein and functions as a molecular chaperone. It is thought to regulate dimerization, DNA binding, and transcriptional activity of basic region-leucine zipper (bZIP) proteins.

Function. Functions as an mRNA export adapter; component of the transcription/export (TREX) complex which is thought to couple mRNA transcription, processing and nuclear export, and specifically associates with spliced mRNA and not with unspliced pre-mRNA. TREX 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 to the cytoplasm via the TAP/NXF1 pathway. Involved in the nuclear export of intronless mRNA; proposed to be recruited to intronless mRNA by ATP-bound DDX39B. Plays a key role in mRNP recognition and mRNA packaging by bridging the mRNP-bound EJC and the TREX core complex. TREX recruitment occurs via an interaction between ALYREF/THOC4 and the cap-binding protein NCBP1. Required for TREX complex assembly and for linking DDX39B to the cap-binding complex (CBC). Binds mRNA which is thought to be transferred to the NXF1-NXT1 heterodimer for export (TAP/NXF1 pathway). In conjunction with THOC5 functions in NXF1-NXT1 mediated nuclear export of HSP70 mRNA; both proteins enhance the RNA binding activity of NXF1 and are required for NXF1 localization to the nuclear rim. Involved in mRNA export of C5-methylcytosine (m5C)-containing mRNAs: specifically recognizes and binds m5C mRNAs and mediates their nucleo-cytoplasmic shuttling. Acts as a chaperone and promotes the dimerization of transcription factors containing basic leucine zipper (bZIP) domains and thereby promotes transcriptional activation. Involved in transcription elongation and genome stability. (Microbial infection) The TREX complex is essential for the export of Kaposi’s sarcoma-associated herpesvirus (KSHV) intronless mRNAs and infectious virus production; ALYREF/THOC4 mediates the recruitment of the TREX complex to the intronless viral mRNA.
Subunit / interactions. Homomultimer; predominantly hexamer when bound to EJC-RNA complex. Component of the transcription/export (TREX) complex at least composed of ALYREF/THOC4, DDX39B, SARNP/CIP29, CHTOP and the THO subcomplex (THOC1, THOC2, THOC3, THOC5, THOC6 and THOC7); in the complex interacts (via UAP56-binding motif) with DDX39B with low affinity but this interaction is likely stabilized by multimerization. TREX seems to have a dynamic structure involving ATP-dependent remodeling; in the complex interacts with THOC1, THOC2 and THOC5. Component of the ALYREF/THOC4-EJC-RNA complex; in the complex interacts (via the WXHD motif) with EIF4A3 and interacts (via the RRM domain) with MAGOH; these interactions are likely specific to RNA-bound EJC. Bridges the THO-DDX39B and EJC-RNA complexes to form the TREX-EJC-RNA complex; this interaction is essential for mRNP recognition and mRNA packaging. Identified in the spliceosome C complex. Found in a mRNP complex with UPF3A and UPF3B. Interacts with RBM8A, RBM15B, NCBP1, LEF1, RUNX1, RNPS1, SRRM1, IWS1 and EXOSC1. Interacts with RBM15B. Interacts with NXF1; the interaction is direct. Interacts with IVNS1ABP (via BACK domain); the interaction is indirect and likely plays a role in mRNA nuclear export. (Microbial infection) Interacts with human Kaposi’s sarcoma-associated herpesvirus (HHV-8) ORF57 protein; this interaction allows efficient export of HHV-8 early and late intronless transcripts. (Microbial infection) Interacts with HHV-1 ICP27 protein; this interaction recruits ALYREF to viral replication compartments and probably directs viral mRNA to the TAP/NXF1 pathway.
Subcellular location. Nucleus. Nucleus speckle. Cytoplasm.
Tissue specificity. Expressed in a wide variety of cancer types.
Post-translational modifications. Arg-204 is dimethylated, probably to asymmetric dimethylarginine. Arginine methylation reduces RNA binding. Citrullinated by PADI4.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 32 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
