Product Usage Information

Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

THOC4/ALY Antibody recognizes endogenous levels of total THOC4/ALY protein.

Species predicted to react based on 100% sequence homology: Hamster, Xenopus, Zebrafish, Bovine, Dog, Guinea Pig, Horse

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala245 of human THOC4/ALY protein. Antibodies are purified by protein A and peptide affinity chromatography.

mRNA export is a process that is tightly coupled to mRNA splicing (1-4). Splicing and packaging of mRNAs in the form of an mRNA-protein complex (mRNP) leads to the recruitment of the mRNA export adaptor THOC4/ALY, via its interaction with the splicing factor UAP56, forming a large complex termed the transcription-export complex (TREX) (1,2,5). THOC4/ALY then directly interacts with NXF1/TAP, a part of the heterodimer that targets the mRNP to the nuclear pore complex, resulting in the shuttling of mRNP out of the nucleus and into the cytoplasm (1-3,6).
