FIGURE 9.

NFRET values representing relative energy transfer between ECFP-HSL and EYFP-linked fatty acid-binding proteins. Gray bars represent basal NFRET, whereas black bars represent energy transfer following addition of forskolin. Error bars represent S.E. (n = 15). C:H refers to ECFP-HSL, whereas each EYFP (Y)-fatty acid-binding protein fusion is indicated by a single letter denoting the adipocyte (A), liver (L), epithelial (E), intestinal (I), or heart (H) forms. The ^* denotes statistical significance (p < 0.05) in the NFRET value (forskolin-stimulated) for the indicated isoform compared with the AFABP/aP2 control.
