Small nuclear ribonucleoprotein Sm D2 is a protein that in humans is encoded by the SNRPD2 gene.^[3][4][5]

The protein encoded by this gene belongs to the small nuclear ribonucleoprotein core protein family. It is required for pre-mRNA splicing and small nuclear ribonucleoprotein biogenesis. Alternative splicing occurs at this locus and two transcript variants encoding the same protein have been identified.^[5]

Interactions

Small nuclear ribonucleoprotein D2 has been shown to interact with DDX20,^[6] Small nuclear ribonucleoprotein D1,^[7][8] Small nuclear ribonucleoprotein polypeptide F,^[7] CDC5L^[9] and SMN1.^[10]
