SRSF4 and cancer: These genes include HNRPD (aka AUF1), CPSF6, SFRS4 (aka SRP75), ZNF638 (aka NP220), PCF11, RBPMS, MSI2, IGF2BP1 (aka CRDBP), and RBM16. The induction of the putative RNA processing protein CROP (cisplatin resistance-associated overexpressed protein) is especially interesting since it is also over-expressed in response to the anti-cancer agent cisplatin [18].
