ID:SNUT1_HUMAN DESCRIPTION: RecName: Full=U4/U6.U5 tri-snRNP-associated protein 1; AltName: Full=SNU66 homolog; Short=hSnu66; AltName: Full=Squamous cell carcinoma antigen recognized by T-cells 1; Short=SART-1; Short=hSART-1; AltName: Full=U4/U6.U5 tri-snRNP-associated 110 kDa protein; AltName: Allergen=Hom s 1; FUNCTION: May play a role in mRNA splicing. May also bind to DNA. SUBUNIT: Identified in the spliceosome C complex. Part of a tri- snRNP complex. INTERACTION: P63165:SUMO1; NbExp=2; IntAct=EBI-607761, EBI-80140; P55854:SUMO3; NbExp=2; IntAct=EBI-607761, EBI-474067; SUBCELLULAR LOCATION: Nucleus. Note=Found in the nucleus of mitogen-activated peripheral blood mononuclear cells (PBMCs), tumor cells, or normal cell lines, but not in normal tissues except testis and fetal liver or in unstimulated PBMCs, suggesting preferential expression in proliferating cells. TISSUE SPECIFICITY: Ubiquitously expressed. PTM: Sumoylated with SUMO2. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. ALLERGEN: Causes an allergic reaction in human. Binds to IgE from atopic dermatitis (AD) patients. Identified as an IgE autoantigen in atopic dermatitis (AD) patients with severe skin manifestations. SIMILARITY: Belongs to the SNU66/SART1 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.
