WebAug 15, 2000 · Increased Ca(2+) signals coupled with reduced release suggest a direct function of CSP in exocytosis downstream from Ca(2+) entry. Because the reduction of evoked release in csp mutants is counteracted by increased Ca(2+) levels, we suggest that CSP primarily increases the Ca(2+) sensitivity of the exocytotic machinery.
