Scaffold proteins assemble vanous signaling molecules into a signalosome and activate signal transduction cascade. These proteins thus provide platforms for receptors, kinases, phosphatases and other effectors into a functional modules (Good et al., 2011). Scaffold proteins are thus key components ofsignaling networks. Among various domain structures in scaffolding proteins, one commonly found is WD40 repeat. Proteins harboring this domain often act as signaling scaffold in which the WD40 repeat domain form a beta propeller structure for assembling signaling molecules.
