Y-box binding protein 1 (YB-1) is encoded by the YBX1 gene in humans. It binds to splice sites in pre-mRNA, regulates splice site selection, and stabilizes cytoplasmic mRNA. YB-1 acts as a transcriptional regulator by: i) controlling the interaction between eukaryotic translation initiation factors and mRNA; and ii) binding to the Y-box motif found in the promoters of genes such as multidrug resistance 1 (MDR1) and HLA class II genes. YB-1 gene expression has been associated with lung cancer and the response to chemotherapy in patients with breast cancer. YB-1 is also known as nuclease sensitive element binding protein 1 (NSEP1), enhancer factor I subunit A, CCAAT-binding transcription factor I subunit A, DNA-binding protein B (DBPB), Y-box transcription factor, BP-8, CSDA2, CSDB1, and MDR-NF1.
This product is an affinity-purified IgG antibody that recognizes human YB-1 protein. The antibody was raised in mouse using recombinant YB-1 protein and can be used for Western blot (WB) detection or immunohistochemical (IHC) detection of human YB-1 protein.
