What is the official name of the VCAN gene?
The official name of this gene is “versican.”
VCAN is the gene's official symbol. The VCAN gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the VCAN gene?
The VCAN gene provides instructions for making a protein called versican. Versican is found in the extracellular matrix of many different tissues and organs. The extracellular matrix is the intricate lattice of proteins and other molecules that forms in the spaces between cells. Versican interacts with many of these proteins and molecules to facilitate the assembly of the extracellular matrix and ensure its stability.
Researchers have proposed several additional functions for versican. This protein likely helps regulate cell growth and division, the attachment of cells to one another (cell adhesion), and cell movement (migration). Studies suggest that versican plays a role in forming new blood vessels (angiogenesis), wound healing, inflammation, and preventing the growth of cancerous tumors. Versican also regulates the activity of several growth factors, which control a diverse range of processes important for cell growth.
Four different versions (isoforms) of the versican protein are produced from the VCAN gene. These isoforms (called V0, V1, V2, and V3) vary by size and by their location within the body.
Does the VCAN gene share characteristics with other genes?
The VCAN gene belongs to a family of genes called PG (proteoglycans).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
