Y box binding protein 1 also known as Y-box transcription factor or nuclease-sensitive element-binding protein 1 is a protein that in humans is encoded by the YBX1 gene.^[3]

Clinical significance

YBX1 is a potential drug target in cancer therapy.^[4] YB-1 helps the replication of adenovirus type 5, a commonly used vector in gene therapy.^[4] Thus, YB-1 can cause an "oncolytic" effect in YB-1 positive cancer cells treated with adenoviruses

Interactions

Y box binding protein 1 has been shown to interact with:

• ANKRD2,^[5]
• CTCF,^[6]
• P53,^[5][7]
• PCNA,^[8]
• RBBP6,^[9] and
• SFRS9.^[10]
