Inositol trisphosphate receptor Ca2+ release channels.
The inositol 1,4,5-trisphosphate (InsP3) receptors (InsP3Rs) are a family of Ca2+ release channels localized predominately in the endoplasmic reticulum of all cell types. They function to releaseExpand

MICU1 Is an Essential Gatekeeper for MCU-Mediated Mitochondrial Ca2+ Uptake that Regulates Cell Survival
Mitochondrial Ca(2+) (Ca(2+)(m)) uptake is mediated by an inner membrane Ca(2+) channel called the uniporter. Ca(2+) uptake is driven by the considerable voltage present across the inner membraneExpand

Inositol 1,4,5-tris-phosphate activation of inositol tris-phosphate receptor Ca2+ channel by ligand tuning of Ca2+ inhibition
Inositol 1,4,5-tris-phosphate (IP3) binding to its receptors (IP3R) in the endoplasmic reticulum (ER) activates Ca2+ release from the ER lumen to the cytoplasm, generating complex cytoplasmic Ca2+Expand

Gain-of-Function Enhancement of IP3 Receptor Modal Gating by Familial Alzheimer’s Disease–Linked Presenilin Mutants in Human Cells and Mouse Neurons
By altering IP3 receptor gating, presenilin mutations associated with familial Alzheimer’s disease increase Ca2+ release from the endoplasmic reticulum. Opening the Calcium Floodgates? Alzheimer’sExpand

Regulation by Ca2+ and Inositol 1,4,5-Trisphosphate (Insp3) of Single Recombinant Type 3 Insp3 Receptor Channels
The inositol 1,4,5-trisphosphate (InsP3) receptor (InsP3R) is an endoplasmic reticulum–localized Ca2+-release channel that controls complex cytoplasmic Ca2+ signaling in many cell types. At leastExpand

EMRE Is a Matrix Ca(2+) Sensor that Governs Gatekeeping of the Mitochondrial Ca(2+) Uniporter.
The mitochondrial uniporter (MCU) is an ion channel that mediates Ca(2+) uptake into the matrix to regulate metabolism, cell death, and cytoplasmic Ca(2+) signaling. Matrix Ca(2+) concentration isExpand

Characterization of ammonia transport by the kidney Rh glycoproteins RhBG and RhCG.
The erythrocyte Rh-associated glycoprotein (RhAG) was recently found to mediate transport of ammonia/ammonium when expressed in Xenopus laevis oocytes and yeast Saccharomyces cerevisiae. NonerythroidExpand
