ZRSR2 (Zinc Finger CCCH-Type, RNA-Binding Motif and Serine/Arginine Rich 2) is a protein involved in RNA splicing, a critical process for generating functional mRNA by removing non-coding introns. It is a component of the minor spliceosome (U12-type), which processes a subset of introns with distinct splice sites. Structurally, ZRSR2 contains CCCH zinc finger motifs and serine/arginine-rich (SR) domains, enabling RNA binding and interactions with splicing machinery.
Mutations in the ZRSR2 gene, particularly in hematopoietic cells, are linked to myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). These mutations, often loss-of-function, disrupt minor intron splicing, leading to aberrant mRNA processing and cellular dysregulation. While less frequent than spliceosome mutations in SF3B1 or U2AF1. ZRSR2 defects are recurrent in MDS and show a male predominance.
Recombinant human ZRSR2 protein is produced using expression systems like bacteria or mammalian cells for functional studies. It aids in elucidating ZRSR2’s role in splicing mechanisms, disease pathways, and interactions with other spliceosomal components. This recombinant tool is vital for developing targeted therapies aiming to correct splicing defects or inhibit malignant cell survival in ZRSR2-mutated cancers. Research on recombinant ZRSR2 also explores its potential as a biomarker for precision oncology approaches.
