Recombinant Human Small nuclear ribonucleoprotein Sm D1 (SNRPD1)

Uniprot Id

P62314

Target Species

Human

Target Name

SNRPD1

Target Full Name

Small nuclear ribonucleoprotein Sm D1

Target Function

Plays a role in pre-mRNA splicing as a core component of the spliceosomal U1, U2, U4 and U5 small nuclear ribonucleoproteins (snRNPs), the building blocks of the spliceosome. Component of both the pre-catalytic spliceosome B complex and activated spliceosome C complexes. Is also a component of the minor U12 spliceosome. May act as a charged protein scaffold to promote snRNP assembly or strengthen snRNP-snRNP interactions through non-specific electrostatic contacts with RNA.

Target Subcellular Location

Cytoplasm, cytosol. Nucleus.

Target Protein Families

SnRNP core protein family

Target Background

This gene encodes a small nuclear ribonucleoprotein that belongs to the SNRNP core protein family. The protein may act as a charged protein scaffold to promote SNRNP assembly or strengthen SNRNP-SNRNP interactions through nonspecific electrostatic contacts with RNA. Two transcript variants encoding different isoforms have been found for this gene.
