Figure 3.

Genomic DNA organization of the 3′ end of the Ob-R gene. The genomic structure of the exons that encode amino acids H₇₉₆–P₈₉₀ of Ob-Rb is shown (see ref. 9). All other splicing variants of the receptor, Ob-Ra, Rc, Rd, and Re, end within the 13-kb region shown. Each exon is identified at the top with an arrow. Introns are represented by solid lines, with their approximate sizes labeled above (not drawn to scale).
