1H-Benzo[d]imidazol-3-ium (Z)-3-carboxyprop-2-enoate

IUCrData, 2016
In the anion of the title molecular salt, C7H7N2+.C4H3O4−, an O—H...O hydrogen bond generates an S(7) graph-set motif while a pair of intermolecular N—H...O and C—H...O hydrogen bonds generate an R44(10) ring-motif.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

An experimental charge density study of the N-H⁺...O⁻ bonds in a proton-transfer system in comparison with regular N-H...O and O-H...N hydrogen bonds [PDF]

, 2004
An experimental charge density study has been carried out on N-H+...O− bonds in the proton-transfer compound piperazinium oxalate as well as on the normal O-H...N bonds in the thiodiglycolic acid-4,4'-bipyridine complex, based on X-ray diffraction ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Methyl 2-oxo-2H-chromene-3-carboxylate [PDF]

, 2012
The title compound, C11H8O4, features an almost planar molecule (r.m.s. deviation = 0.033 Å for all non-H atoms). In the crystal, the molecules are linked via C-H...O hydrogen bonds, forming two-dimensional networks lying parallel to (1-21)
