While highlighting the dynamics of the PTH1R-arr2 complex, MD simulations revealed its overall stability and robust key interactions within the interface, including both at the 7TM domain and phosphorylation clusters of the C-terminal tail of PTH1R. Biol. In general, the orientations are limited by the membrane anchoring of C-edge with pitch angle showing a modest ~13 degrees deviation, followed by ~17 degrees of roll and up to 25 degrees of yaw deviations. However, some interactions at solvent/membrane-exposed region were more dynamic (Supplementary Figs. 67, 310337 (2015). Identify the highlighted structure. Curr. Expert Answer.

Always has one free Vertebrate Histology (BIOLOGY 364) Fall 2015 Lecture Final (Take-home) B) stomach For example, some arr2 residues, such as F75, K107, K157, and K160, are crosslinking hubs involved in as many as 813 crosslinks, resulting in steric overcrowding in static models (Supplementary Fig. ce Crosslinking matrix for Cys-PTH1R positions (row) with BrEtY-arr2 positions (column). Because each crosslinking pair is identified in an independent experiment, the proximity requirements for the formation of Cys-BrEtY adduct are not expected to be all satisfied simultaneously by a single conformational snapshot of the flexible complex. To investigate whether our crosslinking pairs may derive from two distinct populations of complexes either in the tail or in the fully engaged tail + core conformation, we have incorporated the photo-crosslinker Bpa in the N-domain (loop between -strands I and II, 160-loop) of an arrestin variant depleted of the finger loop (Y63K77) (Supplementary Fig. 40, D370D376 (2012).
