Crosstalk between junctional membrane proteins is vital in the coordinated generation of cellular Ca signals. New evidence (Ivanova et al.) reveals the signaling lipid, phosphatidylinositol 4,5-bisphosphate (PIP) reaches across plasma membrane (PM)-endoplasmic reticulum (ER) junctions to regulate inositol 1,4,5-trisphosphate receptors, controlling the critical progression of local to global Ca signals mediating a spectrum of fundamental cellular responses.

Ca signal-generation through inter-membrane junctional coupling between endoplasmic reticulum (ER) STIM proteins and plasma membrane (PM) Orai channels, remains a vital but undefined mechanism. We identify two unusual overlapping Phe-His aromatic pairs within the STIM1 apical helix, one of which (F394-H398) mediates important control over Orai1-STIM1 coupling. In resting STIM1, this locus is deeply clamped within the folded STIM1-CC1 helices, likely near to the ER surface.

Electric potentials referred to as the gravielectric effect (∆ΨS) are generated in a double-membrane system containing identical polymer membranes set in horizontal planes and separating non-homogenous electrolyte solutions. The gravielectric effect depends on the concentration and composition of the solutions and is formed due to the gravitational field breaking the symmetry of membrane complexes/concentration boundary layers formed under concentration polarization conditions. As a part of the Kedem-Katchalsky formalism, a model of ion transport was developed, containing the transport parameters of membranes and solutions and taking into account hydrodynamic (convective) instabilities.

Stress Responses Elicited by Misfolded Proteins Targeted to Mitochondria.

The double-membrane-bound architecture of mitochondria, essential for ATP production, sub-divides the organelle into inter-membrane space (IMS) and matrix. IMS and matrix possess contrasting oxido-reductive environments and discrete protein quality control (PQC) machineries resulting inherent differences in their protein folding environments. To understand the nature of stress response elicited by equivalent proteotoxic stress to these sub-mitochondrial compartments, we took misfolding and aggregation-prone stressor proteins and fused it to well described signal sequences to specifically target and impart stress to yeast mitochondrial IMS or matrix.

Article Synopsis
  • Gram-negative bacteria have a specialized envelope structure consisting of inner and outer membranes with a peptidoglycan layer in between, crucial for protein transport across the inner membrane via the Sec translocon (SecYEG).
  • Protein transport is aided by additional complexes like SecDF-YajC and YidC, as well as chaperones (e.g., SurA, Skp, DegP) that assist in protein folding and quality control in the periplasm.
  • The review suggests that there may be a connection between the Sec and BAM translocons that allows proteins to move to the outer membrane, possibly involving energy coupling mechanisms for effective transport.
