We have cloned the human genes coding for desmosomal glycoproteins DGII and DGIII, found in desmosomal cell junctions, and sequencing shows that they are related to the cadherin family of cell adhesion molecules. Thus a new super family of cadherin-like molecules exists which also includes the other major desmosomal glycoprotein, DGI (Wheeler, G. N., Parker, A. E., Thomas, C. L., Ataliotis, P., Poynter, D., Arnemann, J., Rutman, A. J., Pidsley, S. C., Watt, F. M., Rees, D. A., Buxton, R. S., and Magee, A. I. (1991) Proc. Natl. Acad. Sci. U.S.A., in press). DGIII differs from DGII by the addition of a 46-base pair exon containing an in-frame stop codon resulting in mature protein molecular weights of 84,633 for DGII and 78,447 for DGIII. The unique carboxyl-terminal region of DGII contains a potential serine phosphorylation site explaining why only DGII is phosphorylated on serine. The cadherin cell adhesion recognition sequence (His-Ala-Val) is replaced by Phe-Ala-Thr, suggesting that DGII/III may be adhesive molecules using a different mechanism.

D010766 Phosphorylation The introduction of a phosphoryl group into a compound through the formation of an ester bond between the compound and a phosphorus moiety. Phosphorylations
D003001 Cloning, Molecular The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells. Molecular Cloning
D003896 Desmosomes A type of junction that attaches one cell to its neighbor. One of a number of differentiated regions which occur, for example, where the cytoplasmic membranes of adjacent epithelial cells are closely apposed. It consists of a circular region of each membrane together with associated intracellular microfilaments and an intercellular material which may include, for example, mucopolysaccharides. (From Glick, Glossary of Biochemistry and Molecular Biology, 1990; Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Desmosome
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
