Protein scaffold function
WebbThrough oligomerization, protein monomers assemble on multiple length scales, into larger and more complex structures such as viral capsids, filaments, and regulatory complexes. It is this structural diversity that makes proteins attractive candidates for use as functionalizable scaffolds. Webb15 sep. 2024 · The scaffold is the framework for assembly at the cytoplasmic domain of a receptor; with the assistance of anchoring proteins it recruits kinases, phosphatases and other enzymes, and, with the assistance of adaptor proteins, other factors which will continue the signal sequence within the cell.Pawson, T.
