Human Gene B3GALT5 (ENST00000380620.8) from GENCODE V38
  Description: Homo sapiens beta-1,3-galactosyltransferase 5 (B3GALT5), transcript variant 4, mRNA. (from RefSeq NM_033172)
RefSeq Summary (NM_001356338): This gene encodes a member of a family of membrane-bound glycoproteins. The encoded protein may synthesize type 1 Lewis antigens, which are elevated in gastrointestinal and pancreatic cancers. Alternatively spliced transcript variants using multiple alternate promoters have been observed for this gene. [provided by RefSeq, Sep 2017].

DESCRIPTION: RecName: Full=Beta-1,3-galactosyltransferase 5; Short=Beta-1,3-GalTase 5; Short=Beta3Gal-T5; Short=Beta3GalT5; Short=b3Gal-T5; EC=2.4.1.-; AltName: Full=Beta-3-Gx-T5; AltName: Full=UDP-Gal:beta-GlcNAc beta-1,3-galactosyltransferase 5; AltName: Full=UDP-galactose:beta-N-acetylglucosamine beta-1,3-galactosyltransferase 5;
FUNCTION: Catalyzes the transfer of Gal to GlcNAc-based acceptors with a preference for the core3 O-linked glycan GlcNAc(beta1,3)GalNAc structure. Can use glycolipid LC3Cer as an efficient acceptor.
PATHWAY: Protein modification; protein glycosylation.
SUBCELLULAR LOCATION: Golgi apparatus membrane; Single-pass type II membrane protein (Potential).
TISSUE SPECIFICITY: Expressed in stomach, jejunum, colon, pancreas, small intestine, testis and gastrointestinal and pancreatic cancer cell lines. Hardly detected in lung, liver, adrenal gland and peripheral blood leukocytes.
SIMILARITY: Belongs to the glycosyltransferase 31 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.

ModBase Predicted Comparative 3D Structure on Q9Y2C3
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.
