Deciphering Mode of Action of Functionally Important Regions in the Intrinsically Disordered Paxillin (Residues 1-313) Using Its Interaction with FAT (Focal Adhesion Targeting Domain of Focal Adhesion Kinase)
Fig 4
In-silico analysis of non-binding of C35.
(a) LD2 crystal structure from PDB id: 1K05 (left) being compared with the LD2 structure in the side view and top view of C35 structure showing the masking of the hydrophobic binding region predicted through HMM based SAM-T08 software. The LD2 binding region and the masking regions are depicted by the bracketed region. (b) Docking control showing FAT (co-ordinates from PDB id: 1K05) and LD2 (co-ordinates from PDB id: 2L6F, NMR model # 1) interaction using Hex 6.3 software. (c) Docking of C35 with FAT showing non-interaction due to masking effect. The sidechains of the active residues are shown as red sticks. The hydrophobic patch—HP2 in FAT molecule, which preferentially binds to LD2 is shown as a space filling model in orange (part of helix 1 of FAT) and grey (part of helix 4 of FAT) colors.
