Descriptions

BID is a proapoptotic member of the BCL2 family that shares only the BH3 domain homology with other members of the family in its amino acid sequence. The full-length BID is inactive and present in the cytosolic fraction of living cells. Upon cleavage by Caspase 8, the C-terminal part of BID translocates to mitochondria and is sufficient to trigger cytochrome c release in isolated mitochondria. The N-terminal segment may serve as an internal inhibitor of proapoptotic activity. The proapoptotic activity of BID is expected to require dissociation of the N-terminal segment including H1(14-29) and H2(33-41).

3 GO annotations of cellular component

Name Definition
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
mitochondrial outer membrane The outer, i.e. cytoplasm-facing, lipid bilayer of the mitochondrial envelope.
mitochondrion A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.

No GO annotations of molecular function

5 GO annotations of biological process

Name Definition
apoptotic mitochondrial changes The morphological and physiological alterations undergone by mitochondria during apoptosis.
hepatocyte apoptotic process Any apoptotic process in a hepatocyte, the main structural component of the liver.
positive regulation of extrinsic apoptotic signaling pathway Any process that activates or increases the frequency, rate or extent of extrinsic apoptotic signaling pathway.
positive regulation of intrinsic apoptotic signaling pathway Any process that activates or increases the frequency, rate or extent of intrinsic apoptotic signaling pathway.
positive regulation of release of cytochrome c from mitochondria Any process that increases the rate, frequency or extent of release of cytochrome c from mitochondria, the process in which cytochrome c is enabled to move from the mitochondrial intermembrane space into the cytosol, which is an early step in apoptosis and leads to caspase activation.
