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)

Regulatory and masking regions around paxillin’s LD2 and LD4 and their circular dichroism spectra.

(a) CD spectra of paxillin LD peptides (LD1-LD5) and constructs: B2, C3, C35 and D2. CD spectra of LD2, LD4, C35 and D2 constructs showed negative bands at 222nm and 206nm and a positive band at 192nm that confirms the presence of alpha helical content thus may behave as folded effector binding sites. However, LD1, LD3, LD5, B2 and C3 do not show the characteristic peaks of secondary structures, thus may behave as unfolded effector binding sites. (b) LD2 regulatory region (54–130) and masking region (167–224) evidenced by constructs B3, B4 and B5. (c) LD4 regulatory region (216–257) and masking region (280–313) evidenced by constructs D1, D2 and E1.
