WebRNA splicing occurs in the spliceosome and is tightly regulated by a variety of splicing factors, including the serine/arginine-rich (SR) protein family [6, 7]. SR proteins are extensively phosphorylated at their RS domains by multiple kinases, and this process is mediated by the predominant enzymes SR-specific protein kinases (SPRKs) [ 8 , 9 ]. offres leclerc voyages
