The first signaling scaffold protein discovered was the Ste5 protein from the yeast Saccharomyces cerevisiae. Three distinct domains of Ste5 were shown to associate with the protein kinases Ste11, Ste7, and Fus3to form a multikinase complex.

WebJun 7, 2016 · Scaffold proteins are available with a wide range of specific tags for isolation, in vivo targeting, imaging and reversible or irreversible surface immobilization. WebShank proteins are multidomain scaffold proteins of the postsynaptic density that connect neurotransmitter receptors, ion channels, and other membrane proteins to the actin cytoskeleton and G-protein-coupled signaling pathways. Shank proteins also play a role in synapse formation and dendritic spine maturation. [7] Clinical significance [ edit]
