Membrane-associated guanylate kinase
The membrane-associated guanylate kinases (MAGUK) are a family of proteins. The MAGUKs are defined by their inclusion of PDZ, SH3 and GUK domains, although many of them also contain regions homologous of CaMKII, WW and L27 domains. The GUK domain that they have is structurally very similar to that of the guanylate kinases, however it is known to be catalytically inactive as the P-Loop which binds ATP is absent. It is thought that the MAGUKs have subfunctionalized the GUK domain for their own purposes, primarily based on its ability to form protein–protein interactions with cytoskeleton proteins, microtubule/actin based machinery and molecules involved in signal transduction.
