Small nuclear ribonucleoprotein Sm D1 is a protein that in humans is encoded by the SNRPD1 gene.

Function

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.

Interactions

Small nuclear ribonucleoprotein D1 has been shown to interact with:

• CDC5L,
• CLNS1A,
• DDX20,
• SMN1, and
• Small nuclear ribonucleoprotein D2
