About

* Synthesizes polylacosamine of N-glycan, particulalry along the GlcNAc(β1-6) N-glycan branch.
* B3GnT2 and B3GnT8 may form a heterocomplex to facilitate polyLacNAc extension.
* B3GNT8 is highly expressed in lung, throat, and ileum. It is further augmented during colon cancer.
* Highly metastatic cell lines may synthesize more N-glycans containing polylactosamines than poorly metastatic cell lines.
