The complex stacking disorder of Fe‐ and Ru‐based 1,1′‐(3,6‐pyrazabolyl)metallocenes

open access: yesActa Crystallographica Section B, EarlyView.
The ferrocene Fc(BHpz)2 and the ruthenocene Rc(BHpz)2 belong to the same order–disorder (OD) polytype family and feature a complex stacking disorder, with different ordered and disordered domains in the same crystal.1,1′‐(3,6‐Pyrazabolyl)ferrocene [Fc(BHpz)2] and the corresponding ruthenocene [Rc(BHpz)2] crystallize as order–disorder (OD) structures ...

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

open access: yesAndrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.
