Y box binding protein 1, officially known as YBX1, but commonly referred to as "YB-1" by researchers, is a human protein.[1] Current research is examining its involvement in cancer, and particularly in the metastasis of cancerous cells or prevention thereof.



Y box binding protein 1 has been shown to interact with RBBP6,[2] PCNA,[3] ANKRD2,[4] SFRS9,[5] CTCF[6] and P53.[4][7]
