Rbm20 regulates titin alternative splicing as a splicing repressor
Titin, a sarcomeric protein expressed primarily in striated muscles, is responsible for maintaining the structure and biomechanical properties of muscle cells. Cardiac titin undergoes developmental size reduction from 3.7 megadaltons in neonates to primarily 2.97 megadaltons in the adult. This size reduction results from gradually increased exon skipping between exons 50 and 219 of titin mRNA. ...
متن کاملRole of Aberrant Alternative Splicing in Cancer
Alternative splicing can alter genome sequence and as a consequence, many genes change to oncogenes. This event can also affect protein function and diversity. The growing number of study elucidate the pathological influence of impaired alternative splicing events on numerous disease including cancer. Here, we would like to highlight the significant role of alternative splicing in cancer biolog...
متن کاملTitin Diversity—Alternative Splicing Gone Wild
Titin is an extremely large protein found in highest concentrations in heart and skeletal muscle. The single mammalian gene is expressed in multiple isoforms as a result of alternative splicing. Although titin isoform expression is controlled developmentally and in a tissue specific manner, the vast number of potential splicing pathways far exceeds those described in any other alternatively spl...
متن کاملReversible phosphorylation differentially affects nuclear and cytoplasmic functions of splicing factor 2/alternative splicing factor.
The Ser/Arg-rich (SR) proteins constitute a family of highly conserved nuclear phosphoproteins that are involved in many steps of mRNA metabolism. Previously, we demonstrated that shuttling SR proteins can associate with translating ribosomes and enhance translation of reporter mRNAs both in vivo and in vitro. Here, we show that endogenous, cytoplasmic splicing factor 2/alternative splicing fac...
متن کاملProcessive phosphorylation of alternative splicing factor/splicing factor 2.
SR proteins, named for their multiple arginine/serine (RS) dipeptide repeats, are critical components of the spliceosome, influencing both constitutive and alternative splicing of pre-mRNA. SR protein function is regulated through phosphorylation of their RS domains by multiple kinases, including a family of evolutionarily conserved SR protein-specific kinases (SRPKs). The SRPK family of kinase...
