Translocator protein (TSPO) is an 18 kDa protein mainly found on the outer mitochondrial membrane. [5] It was first described as peripheral benzodiazepine receptor ( PBR ), a secondary binding site for diazepam , but subsequent research has found the receptor to be expressed throughout the body and brain. [ 6 ]
The translocon (also known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes. [1] In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or lumenal) space of the endoplasmic reticulum (ER) from ...
Translocase is a general term for a protein that assists in moving another molecule, usually across a cell membrane. These enzymes catalyze the movement of ions or molecules across membranes or their separation within membranes.
The complete mitochondrial protein translocase complex includes at least 19 proteins: several chaperones, four proteins of the outer membrane translocase (Tom) import receptor, five proteins of the Tom channel complex, five proteins of the inner membrane translocase (Tim) and three "motor" proteins.
PK 11195 is an isoquinoline carboxamide which binds selectively to the peripheral benzodiazepine receptor (PBR) (also known as the mitochondrial 18 kDa translocator protein or TSPO). It is one of the most commonly used PBR ligands due to its high affinity for the PBR in all species, [ 1 ] although it is starting to be replaced by newer and more ...
Adenine nucleotide translocator (ANT), also known as the ADP/ATP translocase (ANT), ADP/ATP carrier protein (AAC) or mitochondrial ADP/ATP carrier, exchanges free ATP with free ADP across the inner mitochondrial membrane. [1] [2] ANT is the most abundant protein in the inner mitochondrial membrane and belongs to the mitochondrial carrier family ...
Basic helix-loop-helix ARNT-like protein 1 or aryl hydrocarbon receptor nuclear translocator-like protein 1 (ARNTL), or brain and muscle ARNT-like 1 is a protein that in humans is encoded by the BMAL1 gene on chromosome 11, region p15.3.
The TIM/TOM complex is a protein complex in cellular biochemistry which translocates proteins produced from nuclear DNA through the mitochondrial membrane for use in oxidative phosphorylation. In enzymology , the complex is described as an mitochondrial protein-transporting ATPase ( EC 7.4.2.3 ), or more systematically ATP phosphohydrolase ...
