	abstract = {The PNT (or Pointed) domain, present within a subset of the Ets family of transcription factors, is structurally related to the larger group of SAM domains through a common tertiary arrangement of four alpha-helices. Previous studies have shown that, in contrast to the PNT. domain from Tel, this domain from Ets-1 contains an additional N-terminal helix integral to its folded structure. To further investigate the structural plasticity of the PNT domain, we have used NMR spectroscopy to characterize this domain from two additional Ets proteins, Erg and GABPalpha. These studies both define the conserved and variable features of the PNT domain, and demonstrate that the additional N-terminal helix is also present in GABPa, but not Erg. In contrast to Tel and Yan, which self-associate to form insoluble polymers, we also show that the isolated PNT domains from Ets-1, Ets-2, Erg, Fli-1, GABPalpha, and Pnt-P2 are monomeric in solution. Furthermore, these soluble PNT domains do not associate in any pair-wise combination. Thus these latter Ets family PNT domains likely mediate interactions with additional components of the cellular signaling or transcriptional machinery. (C) 2004 Elsevier Ltd. All rights reserved.},

	abstract = {Similar size and shape molecules with different electric multipoles are used to investigate effects of molecular dipole, quadrupole, and polarizability interactions on the average orientational order of solutes in nematic liquid crystals. Solutes are codissolved in the same sample tube so that the orientational ordering among solutes can be directly compared and analyzed using mean-field models. Permanent dipoles have a negligible influence on solute orientational order. Effects from molecular polarizability interactions could not be separated from short-range interactions. However, order parameters predicted from strong, short-range repulsive forces coupled with interactions between the solute quadrupole and the average electric field gradient felt by the solute are consistent with experimental values. For the nematic mixture 55 wt\% ZLI 1132 in EBBA [N-(pethoxybenzylidene)-p{\textquoteright}-n-butylaniline] the contribution to solute ordering from long-range electrostatic interactions is negligible.
