Table I. Colocalization of secretory granules with clusters.

Secretory granules (NPY–GFP)	Positive (%)	Negative (%)	Neutral (%)
Syntaxin 1 (n = 10)	62.3 ± 4.9	26.8 ± 5.3	11.1 ± 1.7
Syntaxin 1 (background)	23.3 ± 3	72.0 ± 3.5	4.8 ± 1.3
SNAP-25 (n = 6)	74.2 ± 2.4	15.2 ± 3.4	10.8 ± 2.5
SNAP-25 (background)	45.5 ± 6.9	45.3 ± 7.9	9.0 ± 3.3

Colocalization was rated as described in Figure 2E where n is the number of membrane sheets (with at least 10 secretory granules per membrane sheet) analyzed for each condition. Values are given as mean ± SEM.
