WebJan 5, 2016 · This is interpreted from observing a larger size of this pool in the absence of Arf6, which implies that Arf6 may, if anything, have a role in reducing this pool. This statement is therefore confusing. We agree with the referees that active Arf6 reduces the readily releasable pool of SVs, as unmasked by the increased RRP in the absence of Arf6.
