| Description | Guanylate kinase ( ) (GK) [ ] catalyzes the ATP-dependent phosphorylation of GMP into GDP. It is essential for recycling GMP and indirectly, cGMP. In prokaryotes (such as Escherichia coli), lower eukaryotes(such as yeast) and in vertebrates, GK is a highly conserved monomeric protein of about 200 amino acids. GK has been shown [ , , ] to be structurally similar to protein A57R (or SalG2R) from various strains of Vaccinia virus.Proteins containing one or more copies of the DHR domain, an SH3 domain as well as a C-terminal GK-like domain, are collectively termed MAGUKs (membrane-associated guanylate kinase homologues) [ ], andinclude Drosophila lethal(1)discs large-1 tumor suppressor protein (gene dlg1); mammalian tight junction protein Zo-1; a family of mammalian synaptic proteins that seem to interact with the cytoplasmic tail of NMDA receptor subunits (SAP90/PSD-95, CHAPSYN-110/PSD-93, SAP97/DLG1 and SAP102); vertebrate 55kDa erythrocyte membrane protein (p55); Caenorhabditis elegans protein lin-2; rat protein CASK; and human proteins DLG2 and DLG3. There is an ATP-binding site (P-loop) in the N-terminal section of GK, which is not conserved in the GK-like domain of the above proteins. However these proteins retain the residues known, in GK, to be involved in the binding of GMP. This signature pattern covers a highly conserved region that contains two arginine and a tyrosine which are involved in GMP-binding. |
