Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

| Function | Galactose (Gal) transferase involved in the synthesis of terminal N-acetyllactosamine (LacNac) unit present on glycan chains of glycoproteins and glycosphingolipids (PubMed:9792633, PubMed:17690104, PubMed:12511560, PubMed:32827291). Catalyzes the transfer of Gal residue via a beta1->4 linkage from UDP-Gal to the non-reducing terminal N-acetyl glucosamine 6-O-sulfate (6-O-sulfoGlcNAc) in the linearly growing chain of both N- and O-linked keratan sulfate proteoglycans. Cooperates with B3GNT7 N-acetyl glucosamine transferase and CHST6 and CHST1 sulfotransferases to construct and elongate mono- and disulfated disaccharide units [->3Galbeta1->4(6- sulfoGlcNAcbeta)1->] and [->3(6-sulfoGalbeta)1->4(6- sulfoGlcNAcbeta)1->] within keratan sulfate polymer (PubMed:17690104). Transfers Gal residue via a beta1->4 linkage to terminal 6-O- sulfoGlcNAc within the LacNac unit of core 2 O-glycans forming 6-sulfo- sialyl-Lewis X (sLex). May contribute to the generation of sLex epitope on mucin-type glycoproteins that serve as ligands for SELL/L-selectin, a major regulator of leukocyte migration (PubMed:12511560). In the biosynthesis pathway of neolacto-series glycosphingolipids, transfers Gal residue via a beta1->4 linkage to terminal GlcNAc of a lactotriaosylceramide (Lc3Cer) acceptor to form a neolactotetraosylceramide (PubMed:9792633). |
| Cellular Location | Golgi apparatus membrane; Single-pass type II membrane protein. Secreted |
| Tissue Location | Highest expression is observed in placenta, pancreas, kidney and heart (PubMed:9792633). Expressed in corneal epithelial cells (PubMed:17690104). |

Background
This gene is one of seven beta-1,4-galactosyltransferase(beta4GalT) genes. They encode type II membrane-bound glycoproteinsthat appear to have exclusive specificity for the donor substrateUDP-galactose; all transfer galactose in a beta1,4 linkage tosimilar acceptor sugars: GlcNAc, Glc, and Xyl. Each beta4GalT has adistinct function in the biosynthesis of different glycoconjugatesand saccharide structures. As type II membrane proteins, they havean N-terminal hydrophobic signal sequence that directs the proteinto the Golgi apparatus and which then remains uncleaved to functionas a transmembrane anchor. By sequence similarity, the beta4GalTsform four groups: beta4GalT1 and beta4GalT2, beta4GalT3 andbeta4GalT4, beta4GalT5 and beta4GalT6, and beta4GalT7. The enzymeencoded by this gene appears to mainly play a role in glycolipidbiosynthesis. Two alternatively spliced transcript variants havebeen found for this gene.
