Multiple transcription initiation and alternative splicing in the 5' untranslated region of the core 2 beta1-6 N-acetylglucosaminyltransferase I gene.

The glycosyltransferase core 2 beta1,6 N-acetylglucosaminyltransferase I (C2GnT I) plays an important regulatory role in the synthesis of biologically significant oligosaccharide structures. This gene is expressed in a variety of cell types, including lymphocytes and mucin-producing cells. The expression pattern of this gene suggests a complex system of regulation.
