RBM20 is a nuclear protein which regulates alternative splicing of expressed genes that have a key role in cardiac function. By cloning the human and mouse RBM20 cDNA, producing expressing vectors for truncated proteins, and comparing their sub-cellular distribution in transfected cells, we have identified the sequences necessary for RBM20 full nuclear retention. The region overlaps an RNA binding motif and a serine-arginine domain. The sequence is conserved in many species but belongs only to RBM20 orthologs. The RMB20 tissue specificity, together with the properties of its nuclear localization determinant, demonstrates a specific evolutionary selection of post-transcriptional regulation factors
