The inner mitochondrial membrane is both an electrical insulator and chemical barrier. Sophisticated ion transporters exist to allow specific molecules to cross this barrier. There are several antiport systems embedded in the inner membrane, allowing exchange of anions between the cytosol and the mitochondrial matrix. [7]
IMMT encodes an inner mitochondrial membrane (IMM) protein in the nucleus. It is posttranslational transported to the IMM. It is posttranslational transported to the IMM. Mic60/Mitofilin (encoded by the IMMT gene) is a core subunit of the MICOS-complex, directly located next to cristae junctions (CJ).
NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 6, also known as complex I-B17, is a protein that in humans is encoded by the NDUFB6 gene. [5] [6] [7] NADH dehydrogenase (ubiquinone) 1 beta subcomplex subunit 6, is an accessory subunit of the NADH dehydrogenase (ubiquinone) complex, located in the mitochondrial inner membrane.
The inner mitochondrial membrane, The cristae space (formed by infoldings of the inner membrane), and; The matrix (space within the inner membrane), which is a fluid. Mitochondria have folding to increase surface area, which in turn increases ATP (adenosine triphosphate) production. Mitochondria stripped of their outer membrane are called ...
In the mitochondrion, the matrix is the space within the inner membrane. The word "matrix" stems from the fact that this space is viscous, compared to the relatively aqueous cytoplasm. The mitochondrial matrix contains the mitochondrial DNA, ribosomes, soluble enzymes, small organic molecules, nucleotide cofactors, and inorganic ions. [1]
Mitochondrial import inner membrane translocase subunit Tim9 is an enzyme that in humans is encoded by the TIMM9 gene. [ 5 ] [ 6 ] [ 7 ] TIMM9 belongs to a family of evolutionarily conserved proteins that are organized in heterooligomeric complexes in the mitochondrial intermembrane space .
The mitochondria-associated ER membranes (MAMs), play role in cell death modulation. Mitochondrial outer membrane permeabilization (MOMP), is a reason of the higher matrix Ca 2+ levels, which is acts as a trigger for apoptosis. MOMP is the process before apoptosis, which is accompanied to permeability of the inner membrane of the mitochondria ...
The enzyme cytochrome c oxidase, also known as Complex IV, is a large transmembrane protein complex found in mitochondria and bacteria. It is the last enzyme in the respiratory electron transport chain located in the inner mitochondrial or bacterial membrane. It receives an electron from each of four cytochrome c molecules, and transfers them ...
