Modeling of the ARNT: SIM1 heterodimeric complex interaction interfaces. SIM1 domain carbons are colored per Figure 1A and residues labeled. Polar contacts between SIM1 and ARNT are shown as yellow dashes. Global context of the complex is given in Figure 1. (A) bHLH SIM1 domain interactions with ARNT are displayed, as described in Section 3.1.1. The SIM1 bHLH domain is colored yellow and ARNT is given in black carbons. (B) PASA SIM1 domain interactions with ARNT are presented, as described in Section 3.1.2. The SIM1 PASA domain is colored cyan or white and ARNT is given in black carbons. (C) PASB SIM1 domain interactions with ARNT are shown, as described in Section 3.1.3. The SIM1 PASB domain is colored blue and ARNT is given in black carbons. (D) PAC SIM1 domain interactions with ARNT are exhibited, as described in Section 3.1.4. The SIM1 PAC domain is colored green and ARNT is given in black carbons.
