Supplementary information

RBPMS also known as RNA Binding Protein with Multiple Splicing is an important component in RNA processing. It weighs approximately 24 kDa and is widely expressed in human tissues with significant presence in the central nervous system and heart. The protein engages directly with RNA molecules impacting their stability and translation. Its structure allows it to bind specifically to RNA influencing the fate of transcripts by modulating their processing and transport.
Biological function summary

RBPMS plays a role in the regulation of gene expression by interacting with other proteins to form ribonucleoprotein complexes. These complexes are important for the post-transcriptional management of gene expression impacting mRNA splicing and localization. RBPMS also exhibits involvement in the development of neuronal cells where it contributes to neuronal differentiation and growth by aiding in the precise processing of specific mRNA transcripts that are essential for neural functions.

Pathways

RBPMS participates in the regulation of the mRNA splicing and transport pathways. It interacts with the spliceosome complex influencing alternative splicing events that generate diverse protein isoforms. RBPMS is associated with proteins such as SMN1 which also plays a part in mRNA processing and is integral to the spliceosomal machinery. These interactions make RBPMS a pivotal mediator in translating genetic information into functional proteins therefore affecting cellular growth and differentiation.

Mutations or altered expression of RBPMS have links to neurodegenerative diseases like amyotrophic lateral sclerosis (ALS) and cardiovascular disorders. In ALS RBPMS along with proteins like TDP-43 becomes misregulated contributing to disease pathogenesis by disrupting normal RNA processing and splicing patterns. In the heart compromised expression levels of RBPMS can lead to aberrant cardiac function where it might associate with proteins such as Troponin T implicating it in heart muscle contraction regulation essential for maintaining cardiac health.

Target data

Isoform A. RNA binding protein that mediates the regulation of pre-mRNA alternative splicing (AS) (PubMed : 24860013, PubMed : 26347403). 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 (By similarity). 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 (By similarity). 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. Can also bind to CA dinucleotide repeats (PubMed : 24860013, PubMed : 26347403). Mediates repression of TPM1 exon 3 by binding to CAC tandem repeats in the flanking intronic regions, followed by higher-order oligomerization and heterotypic interactions with other splicing regulators including MBNL1 and RBFOX2, which prevents assembly of ATP-dependent splicing complexes (By similarity).. Isoform C. Acts as a regulator of pre-mRNA alternative splicing (AS) (By similarity). Binds mRNA (PubMed : 17099224). Regulates AS of ACTN1, FLNB, although with lower efficiency than isoform A / RBPMSA (By similarity). Acts as coactivator of SMAD transcriptional activity in a TGFB1-dependent manner, possibly through increased phosphorylation of SMAD2 and SMAD3 at the C-terminal SSXS regions and promotion of the nuclear accumulation of SMAD proteins (PubMed : 17099224).
