FIG. 4.

(A) CD36 binding assays for different CIDR chimeric constructs. CIDR-105Δ and CIDR-Δ106 totally lost binding ability (see Fig. 2A for the nomenclature of the constructs). The 1640-f chimera binds as well as CIDR-f to the CD36 receptor molecule. Results are expressed as means and standard deviations from three independent experiments. (B) Peptide inhibition of the interaction between CIDR and CD36. The binding of both CIDR-f and the 1640-f chimera to CD36 is competed by the CD36:145-171 peptide in a concentration-dependent manner.
