| 背景 | RNA-binding protein with multiple splicing (RBPMS) is a ~21 kDa protein. RNA binding protein that mediates the regulation of pre-mRNA alternative splicing (AS). Acts either as activator (FLNB, HSPG2, LIPA1, MYOCD, PTPRF and PPFIBP1) or repressor (TPM1, ACTN1, ITGA7, PIEZO1, LSM14B, MBNL1 and MBML2) of splicing events on specific pre-mRNA targets. Together with RNA binding proteins RBFOX2 and MBNL1/2, activates a splicing program associated with differentiated contractile vascular smooth muscle cells (SMC) by regulating AS of numerous pre-mRNA involved in actin cytoskeleton and focal adhesion machineries, suggesting a role in promoting a cell differentiated state. Binds to introns, exons and 3'-UTR associated with tandem CAC trinucleotide motifs separated by a variable spacer region, at a minimum as a dimer. The minimal length of RNA required for RBPMS-binding tandem CAC motifs is 15 nt, with spacing ranging from 1 to 9 nt. 1. Farazi, TA. et al. (2014) RNA (New York, N.Y.) 20, 1090-102. PMID: 248600132.
