SRSF2 (SC35) is a 25 kDa member of the serine/arginine-rich (SR) family of splicing factors. It contains a single RNA recognition motif (RRM) at the N-terminus and an RS domain (arginine/serine-rich) at the C-terminus.
SRSF2 Protein (Serine/Arginine-Rich Splicing Factor 2) is a 248-amino acid RNA-binding protein encoded by the SRSF2 gene located on chromosome 17q25.2. This protein is a member of the serine/arginine (SR) family of splicing factors and contains an RNA recognition motif (RRM) at its N-terminus and an RS domain at its C-terminus. SRSF2 plays critical roles in both constitutive and alternative splicing.
Mutations in SRSF2 are commonly found in myelodysplastic syndromes (MDS) and related hematological disorders. These mutations alter the splicing patterns of target genes, affecting cell proliferation, differentiation, and survival. The protein is also involved in mRNA export and translation regulation.
Spliceosome-modulating compounds (E7107, H3B-8800) affect SRSF2 function indirectly by altering spliceosome assembly. No direct SRSF2-targeting drugs are currently in clinical use.
The study of Srsf2 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
