hnRNP‐K, a multifaceted RNA‐ and DNA‐binding protein associated with pre‐mRNA, mRNA metabolism and transport (Dejgaard and Leffers, 1996; Lu and Gao, 2016), has been shown to contribute to metastasis in several cancer types (Chung et al., 2014; Gao et al., 2013; Zhang et al., 2016b; Zhou et al., 2010). The gene discussed is HNRNPK; the disease is cancer.
