Solute channels of the outer membrane: from bacteria to chloroplasts [PDF]

, 2007
Chloroplasts, unique organelles of plants, originated from endosymbiosis of an ancestor of today's cyanobacteria with a mitochondria-containing host cell. It is assumed that the outer envelope membrane, which delimits the chloroplast from the surrounding

Fully Additive Vertical Organic Electrochemical Transistors on Renewable and Compostable Substrates Enable Ultrasensitive Bioelectronics

Advanced Functional Materials, EarlyView.
Fully additive vertical organic electrochemical transistors (vOECTs) with channel‐length of 226 nm on a 50 µm compostable substrate achieve >106 current modulation and ∼36 mS transconductance. Ion‐selective integration enables 1.1 mA dec−1 sensitivity and 36 µm detection limit, highlighting a scalable platform for sustainable electronics and ...

Tissue-specific expression of calcium channels [PDF]

, 1993
The high-voltage-activated calcium channel is a multimeric protein complex containing 1, 2/δ, β, and γ subunits. The 1 subunit is the ion conduction channel and contains the binding sites for calcium channel blockers and toxins.

Nitrate-Sialin2 axis couples ER-mitochondrial calcium signaling with fatty acid metabolism to drive white adipose browning

Nature Communications
White adipose browning is a promising route to restore energy balance; however, how inorganic anion signals engage intracellular organelle networks to drive this process remains unclear. Here, we identify Sialin2 as a nitrate sensor that converts dietary

A schistosome [beta] subunit remodels inactivation of a calcium channel _via_ an N-terminal polyacidic motif [PDF]

, 2010
The beta subunit of high voltage-activated Ca (Cav) channels targets the pore forming [alpha]~1~ subunit to the plasma membrane and defines the biophysical phenotype of the Cav channel complex. Cav channel inactivation following activation and opening is

Downregulation of voltage-dependent anion channel-1 expression by RNA interference prevents cancer cell growth in vivo [PDF]

Cancer Biology & Therapy, 2010
The voltage-dependent anion channel 1 (VDAC1), located at the outer mitochondrial membrane (OMM), is a key protein in regulating the exchange of ions, nucleotides and a variety of metabolites in and out of the mitochondria. As such, VDAC serves a crucial role in cellular energy maintenance.

Fast and slow voltage-dependent dynamics of magnesium block in the NMDA receptor: the asymmetric trapping block model

, 2004
The NMDA receptor (NMDAR) produces a long-lasting component of the glutamatergic EPSC in mammalian central neurons. The current through NMDARs is voltage dependent as a result of block by extracellular magnesium, which has recently been shown to give ...
