Cell membranes
Weak glycolipid binding of a microdomain-tracer peptide correlates with aggregation and slow diffusion on cell membranes.
... Our results that more aggregation-prone species of the peptide interact less well with the membrane are perhaps surprising in light of the fact that toxins such as CtxB bind more tightly upon oligomerization, as one ...
