Overall, these observations suggest a function for the N-edge of arrestins in recruiting and/or stabilizing the GPCR C-terminus. Indeed, while only about half of the pairwise crosslinks strictly satisfy the 10.2 Cys-BrEtY C-C distance in the static model, most of them (96%) come within this distance at some point during unbiased MD simulations, with the six outliers coming within 15. and Y.A. A. Does cell division occur within the basal or surface layer of the cell? Although the interactions can switch between several positively charged side-chains of arr2 in the model, this position well satisfies other crosslinking proximity restraints and might contribute to the overall complex stability (Fig. Get the most important science stories of the day, free in your inbox.
