ABC of multifaceted Dystrophin glycoprotein complex (DGC).

Dystrophin protein in association with several other cellular proteins and glycoproteins leads to the formation of a large multifaceted protein complex at the cell membrane referred to as dystrophin glycoprotein complex (DGC), that serves distinct functions in cell signalling and maintaining the membrane stability as well as integrity. In accordance with this, several findings suggest exquisite role of DGC in signalling pathways associated with cell development and/or maintenance of homeostasis. In the present review, we summarize the established facts about the various components of this complex with emphasis on recent insights into specific contribution of the DGC in cell signalling at the membrane. We have also discussed the recent advances made in exploring the molecular associations of DGC components within the cells and the functional implications of these interactions. Our review would help to comprehend the composition, role and functioning of DGC and may lead to a deeper understanding of its role in several human diseases. This article is protected by copyright.
