Genes in this family provide instructions for making enzymes that act as (or are predicted to act as) glycosyltransferases. Glycosyltransferases modify proteins by adding sugar molecules to them through a process called glycosylation. The sugar is transferred from one protein, called the donor, to another, called the acceptor. Some glycosyltransferases glycosylate themselves.
Glycosylation is critical for the normal function of the acceptor protein. For example, the LARGE protein, produced from a gene in this family, glycosylates a protein called alpha (α)-dystroglycan, which anchors cells in the correct position. Without glycosylation, α-dystroglycan loses its ability to anchor cells, which impairs normal muscle, brain, and eye development and leads to a severe condition called Walker-Warburg syndrome. Glycosylation by enzymes produced from other genes in this family is important for the storage of energy and cellular signaling.
The HUGO Gene Nomenclature Committee (HGNC) provides an index of gene families (http://www.genenames.org/cgi-bin/genefamilies/) and their member genes.
