Amphiphilicity of Tetraazaporphyrins Containing Four Terminal Carboxylic Acid and Four Alkyl Groups Promotes Face-On Orientation in Langmuir Films

Author(s): Alinia Z; Abdulhamied E; Selmani S; Miclette Lamarche R; Eichhorn SH; DeWolf CE;

Control over the orientation of polycyclic aromatic dyes in thin films is paramount to tailoring their optical, electronic, and mechanical properties. Their supramolecular assembly in films is tuned here by converting the macrocyclic dyes to large amphiphiles. Two octaalkythio-substituted tetraazaporphyrins (TAPs) with one 5-carboxypentyl and one pentyl o ...

Tuning Electrostatics to Promote Ordered Monolayers of Phosphole-Lipids

Author(s): Alinia Z; Miao D; Baumgartner T; DeWolf CE;

Heteroatom-doped p-conjugated systems have been exploited for electronic device applications. Phosphole-containing backbones are particularly intriguing with regard to electron delocalization and ultimately control over the photophysical, redox, and charge transfer characteristics. However, practical application of these materials commonly relies on well- ...

Interactions between the Cell Membrane Repair Protein S100A10 and Phospholipid Monolayers and Bilayers

Author(s): Yan X; Kumar K; Miclette Lamarche R; Youssef H; Shaw GS; Marcotte I; DeWolf CE; Warschawski DE; Boisselier E;

Protein S100A10 participates in different cellular mechanisms and has different functions, especially at the membrane. Among those, it forms a ternary complex with annexin A2 and the C-terminal of AHNAK and then joins the dysferlin membrane repair complex. Together, they act as a platform enablin ...

AHNAK C-Terminal Peptide Membrane Binding-Interactions between the Residues 5654-5673 of AHNAK and Phospholipid Monolayers and Bilayers.

Author(s): Yan X, Noël F, Marcotte I, DeWolf CE, Warschawski DE, Boisselier E

The dysferlin membrane repair complex contains a small complex, S100A10-annexin A2, which initiates membrane repair by recruiting the protein AHNAK to the membrane, where it interacts via binding sites in the C-terminal region. However, no molecular data are available for the membrane binding of the various proteins involved in this complex. Therefore, th ...
