Genomic organization of TNFR2 and its interaction with TNF-α. A: The TNFRSF1B gene organization on chromosome 1p36.2, consisting of 10 exons ranging from 35 to 2489 bp and 9 introns ranging from 338 to 7500 bp, totals 26 kb. B: Schematic representation of CRD 1–4 of TNFR2 indicating the component of each CRD of the two modules (A1, A2, B1 or B2), CRD 1 (PLAD; A1 and B2), CRD 2 (A1 and B2), CRD 3 (A2 and B1), and CRD 4 (A1 and B2). C: Showing the crystal structure of the 3ALQ (Protein Data Bank ID) of the TNFR2/TNF-α complex, indicating the confirmational interaction between three units of TNFR2 and three units of TNF-α. TNFR2, tumor necrosis factor receptor type 2; tTNF-α, triple tumor necrosis factor; TM, transmembrane; UTR, untranslated region; CRD, cysteine-rich domain; PLAD, pre-ligand assembly domain; kb, kilobases; bp, base pairs; (*), three identical TNFR2 units
