ID:SMD1_HUMAN DESCRIPTION: RecName: Full=Small nuclear ribonucleoprotein Sm D1; Short=Sm-D1; AltName: Full=Sm-D autoantigen; AltName: Full=snRNP core protein D1; FUNCTION: May act as a charged protein scaffold to promote snRNP assembly or strengthen snRNP-snRNP interactions through nonspecific electrostatic contacts with RNA. SUBUNIT: Identified in the spliceosome C complex. Component of the U11/U12 snRNPs that are part of the U12-type spliceosome. INTERACTION: P54105:CLNS1A; NbExp=5; IntAct=EBI-372177, EBI-724693; SUBCELLULAR LOCATION: Nucleus. PTM: Methylated on arginine residues by PRMT5 and PRMT7; methylation is required for assembly and biogenesis of snRNPs. MISCELLANEOUS: In the autoimmune disease systemic lupus erythematosus, antinuclear antibodies are developed with Sm specificity. SIMILARITY: Belongs to the snRNP core protein family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
