scaffold protein

Function

• proteins that provide a scaffold for the assembly of multiprotein signaling complexes & cytoskeletal anchoring at synaptic membranes & possibly other plasma membranes
• in the post synaptic density of excitatory synapses, the scaffold proteins assemble a complex around glutamate receptors, including NMDA receptors & AMPA receptors
• the scaffold proteins function in signal transduction, cytoskeletal anchoring & trafficking of the glutamate receptors

Compartment

• plasma membrane, synaptic membrane, post-synpatic density
• the scaffold proteins may localize to regions of lipid rafts

More general terms

• membrane protein
