Our Abpromise guarantee covers the use of ab109918 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/250. Detects a band of approximately 59 kDa (predicted molecular weight: 64 kDa).|
FunctionCatalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Has a broad spectrum of substrates for peptides such as EA2, Muc5AC, Muc1a, Muc1b and Muc7.
Tissue specificityWidely expressed. Expressed in all tissues tested.
PathwayProtein modification; protein glycosylation.
Sequence similaritiesBelongs to the glycosyltransferase 2 family. GalNAc-T subfamily.
Contains 1 ricin B-type lectin domain.
DomainThere are two conserved domains in the glycosyltransferase region: the N-terminal domain (domain A, also called GT1 motif), which is probably involved in manganese coordination and substrate binding and the C-terminal domain (domain B, also called Gal/GalNAc-T motif), which is probably involved in catalytic reaction and UDP-Gal binding.
The ricin B-type lectin domain directs the glycopeptide specificity. It is required in the glycopeptide specificity of enzyme activity but not for activity with naked peptide substrates, suggesting that it triggers the catalytic domain to act on GalNAc-glycopeptide substrates.
Cellular localizationSecreted and Golgi apparatus > Golgi stack membrane.

Predicted band size: 64 kDa
Exposure time: 20 minutes
We hypothesize that the band observed at 59 kDa represents the soluble form of GALNT1 due to the presence of a 40 amino acid signal peptide. This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab109918 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
