Figure 8. Working model of Sec18p regulation by PA.

Figure 8

Sec18p associates with vacuole membranes through direct interactions with PA. Upon PA hydrolysis by Pah1p, Sec18p is no longer sequestered on the membrane away from cis-SNAREs and is recruited to them to carry out priming activity. Red ovals depict PA’s phosphate headgroup. Blue ovals depict generic lipid head groups.
