SNRPD1 - small nuclear ribonucleoprotein D1 polypeptide Gene

Homo sapiens

Also known as SMD1; SNRPD; Sm-D1; HsT2456

Gene ID: 6632 | Gene type: protein coding

About SNRPD1

Cytogenetic location: 18q11.2 Genomic coordinates (GRCh38): 18:21,612,314-21,633,520 (from NCBI)

This gene has 4 transcripts (splice variants), 234 orthologues and 2 paralogues. Ubiquitous expression in lymph node (RPKM 17.9), bone marrow (RPKM 15.5) and 25 other tissues.

Summary

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. [provided by RefSeq, May 2014]
