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.^[5] YBX1 is an RNA binding protein^[6] that stabilises messenger RNAs modified with N6-methyladenosine.^[7]

Clinical significance

YBX1 is a potential drug target in cancer therapy.^[8] YB-1 helps the replication of adenovirus type 5, a commonly used vector in gene therapy.^[8] 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:
