PCBP1 is as yet not classified as a driver (Futreal et al, 2004), but it is involved in the regulation of the expression of a number of cancer genes and has been previously implicated in tumorigenesis and metastasis (Wang et al, 2010; Huo et al, 2012; Wagener et al, 2015; Zhou & Tong, 2015). The gene discussed is PCBP1; the disease is cancer.
