small nuclear ribonucleoprotein D3 polypeptide 18kDa
Small nuclear ribonucleoprotein Sm D3
snRNP core protein D3
FunctionAppears to function in the U7 snRNP complex that is involved in histone 3'-end processing. Binds to the downstream cleavage product (DCP) of histone pre-mRNA in a U7 snRNP dependent manner.
Sequence similaritiesBelongs to the snRNP core protein family.
Post-translational modificationsMethylated on arginine residues by PRMT5 and PRMT7; methylation is required for assembly and biogenesis of snRNPs. Arg-97 is dimethylated, probably to asymmetric dimethylarginine.
