【多选题】Unstructured sequences have important roles in the functions of a protein:
A.
Being able to flex and bend, they can wrap around one or more target proteins like a scarf, binding with both high specificity and low affinity.
B.
By forming flexible tethers between the compact domains in a protein, they provide flexibility while increasing the frequency of encounters between the domains.
C.
They can help scaffold proteins bring together proteins in an intracellular signaling pathway, facilitating interactions.
D.
They also give proteins like elastin the ability to form rubberlike fibers, allowing our tendons and skin to recoil after being stretched.
