Small nuclear ribonucleoprotein Sm D2 (SNRPD2)

Small nuclear ribonucleoprotein Sm D2 (SNRPD2) is a core protein of the spliceosomal small nuclear ribonucleoproteins (snRNPs), essential components of the spliceosome that mediate pre-mRNA splicing in eukaryotic cells. SNRPD2 forms part of the Sm protein heptameric ring structure in major and minor spliceosomes (U1, U2, U4, U5, and U12 snRNPs). It plays critical roles in pre-mRNA splicing, snRNP biogenesis, sister chromatid cohesion, cell proliferation, and nuclear retention of some lncRNAs. Altered expression or function of SNRPD2 has been implicated in cancer prognosis, neurodegenerative disease risk, and rare congenital syndromes. While SNRPD2 itself is not a direct therapeutic target, it may be modulated in disease by post-translational modifications such as ubiquitination, and its levels or modifications could serve as disease biomarkers[4][5][7][8][10]. Note: - SNRPD2 is not classified as a typical drug target (e.g., receptor, enzyme, or transporter), and there are no known drugs that specifically interact with or inhibit SNRPD2 for therapeutic purposes[4][5][7][10]. - The submitted aliases contained several duplications and conflations with SNRPD1; SNRPD2 and SNRPD1 are distinct core proteins within the snRNP family[9].
