Geranylgeranylation is a type of post-translational modification involving the attachment of a geranylgeranyl group to a protein. The geranylgeranyl group is a 20-carbon isoprenoid compound formed by the condensation of two molecules of farnesyl (a 15-carbon isoprenoid). This modification is crucial for the proper functioning, localization, and stability of various proteins within the cell.
