As a member of the RNA recognition motif (RRM) family of RBPs, RNA-binding protein 38 (RBM38, also called RNPC1) has been shown to function as a tumor suppressor in breast cancer [5], acute myeloid leukemia [6], colorectal cancer [7], and correlates with improved survival in human ovarian cancer [8]. This evidence concerns the gene RBM38 and breast carcinoma.
