Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro365 of human UAP56 protein.

Background

The UAP56 gene is found in the central MHC region and encodes a member of the DEAD-box family of RNA helicases (1). Also known as DDX39B and BAT1, UAP56 functions as an ATP-dependent splicing factor and RNA helicase in the evolutionary conserved transcription/export (TREX) complex. The TREX complex is recruited to sites of active transcription, where it travels along the length of the gene with RNA polymerase II and exports resulting mRNAs to the cytoplasm (2-8).

DDX39, also known as DDX39A, is a DEAD-box helicase highly homologous to UAP56 and is upregulated in lung squamous cell cancers (9,10). DDX39 has been shown to bind to TRF2 to regulate telomere protection (11). Furthermore, DDX39 is overexpressed in several cancer types, which is associated with poor prognosis (12-15). Both UAP56 and DDX39 are hijacked by various viral replication machineries to enable viral reproduction and mRNA export (16-18). UAP56 and DDX39 have also been implicated in promoting the AR-V7 splice variant in advanced prostate cancers (19).
