WebMar 15, 2024 · In humans, splicing involves a series of reactions catalyzed by a large ribonucleoprotein complex called the spliceosome, which recognizes key regulatory sequences on the pre-mRNA. The two bases at each extremity of the intron constitute the canonical donor (GU) and acceptor (AG) splice sites. WebThe serine-arginine rich splicing factor 1 (SRSF1 or ASF/SF2) has been shown to function as an oncoprotein and is upregulated in many cancers and other age-related disorders. Indeed, SRSF1 inhibition results in a splicing ratio in the LMNA pre-mRNA favoring lamin A production over that of progerin.
