Alternative splicing in the RBMXL1 5'-UTR induces uORF-mediated translation control in activated B lymphocytes.

ABSTRACT: The RNA binding motif X-linked (RBMX) gene plays multiple roles in gene transcription and alternative splicing regulation. Modifications to its expression have been associated with the development of various cancers. In addition to RBMX, there exist several RBMX-like genes (RBMXLs) that have been generated by retrotransposition of RBMX. Among these, RBMXL1 encodes a protein that is more than 95% identical to RBMX and may therefore fulfil similar functions. This study identified a specific variation in the alternative splicing of a small exon located in the 5'-untranslated region of the human RBMXL1 mRNA. This occurs following the infection of primary B lymphocytes by the Epstein-Barr virus (EBV) or their activation by a combination of CD40 Ligand and Interleukin 4. The inclusion of this sm
