SNRPD1 - small nuclear ribonucleoprotein D1 polypeptide Gene
Also Known as SMD1; SNRPD; Sm-D1; HsT2456
Species: Homo sapiens
About SNRPD1
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]
