TF (tissue factor) is a transmembrane cofactor that initiates blood coagulation in mammals by binding Factor VIIa to activate Factors X and IX. The cofactor can reside in a cryptic configuration on primary cells and de-encryption may involve a redox

Interactions between the transmembrane domains of phospholamban (PLB) and the cardiac Ca2+ pump (SERCA2a) have been investigated by chemical cross-linking. Specifically, C-terminal, transmembrane residues 45-52 of PLB were individually mutated to Cys, then cross-linked to V89C in the M2 helix

The DNase I binding loop (residues 38-52), the hydrophobic plug (residues 262-274), and the C terminus region are among the structural elements of monomeric (G-) actin proposed to form the intermonomer interface in F-actin. To test the proximity and interactions

Membrane-intrinsic enzymes are embedded in lipids, yet how such enzymes interrogate lipid substrates remains a largely unexplored fundamental question. The outer membrane phospholipid:lipid A palmitoyltransferase PagP combats host immune defenses during infection and selects a palmitate chain using its beta-barrel

Molecular pharmacology, 78(4), 723-733 (2010-07-16)
Glutathione transferase P1-1 (GSTP1-1) plays crucial roles in cancer chemoprevention and chemoresistance and is a key target for anticancer drug development. Oxidative stress or inhibitor-induced GSTP1-1 oligomerization leads to the activation of stress cascades and apoptosis in various tumor cells.
