Small nuclear ribonucleoprotein Sm D2 is a protein that in humans is encoded by the SNRPD2 gene.^[1]^[2]^[3]

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.^[3]

Interactions

Small nuclear ribonucleoprotein D2 has been shown to interact with DDX20,^[4] Small nuclear ribonucleoprotein D1,^[5]^[6] Small nuclear ribonucleoprotein polypeptide F,^[5] CDC5L^[7] and SMN1.^[8]
