Integrin recycle
NettetIntegrin β1 recycling may depend upon an activation of protein kinase C that GRP1 cannot respond to. Thus, future investigations into the mechanisms underlying the differing actions of ARNO and GRP1 during integrin β1 recycling will likely provide a better understanding of how migration is regulated by ARF.

We find that external stimulation mainly impacts on its recycling from the recycling endosome, rather than its accumulation at this compartment.
