The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
GO:0016020 |
membrane |
cellular_component |
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
GO:0007155 |
cell adhesion |
biological_process |
The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules. |
GO:0005886 |
plasma membrane |
cellular_component |
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
GO:0006915 |
apoptotic process |
biological_process |
A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died. |
GO:0030054 |
cell junction |
cellular_component |
A cellular component that forms a specialized region of connection between two or more cells, or between a cell and the extracellular matrix, or between two membrane-bound components of a cell, such as flagella. |
GO:0042981 |
regulation of apoptotic process |
biological_process |
Any process that modulates the occurrence or rate of cell death by apoptotic process. |
GO:0070268 |
cornification |
biological_process |
A type of programmed cell death that occurs in the epidermis, morphologically and biochemically distinct from apoptosis. It leads to the formation of corneocytes, i.e. dead keratinocytes containing an amalgam of specific proteins (e.g., keratin, loricrin, SPR and involucrin) and lipids (e.g., fatty acids and ceramides), which are necessary for the function of the cornified skin layer (mechanical resistance, elasticity, water repellence and structural stability). |
GO:0030057 |
desmosome |
cellular_component |
A cell-cell junction in which: on the cytoplasmic surface of each interacting plasma membrane is a dense plaque composed of a mixture of intracellular anchor proteins; a bundle of keratin intermediate filaments is attached to the surface of each plaque; transmembrane adhesion proteins of the cadherin family bind to the plaques and interact through their extracellular domains to hold the adjacent membranes together by a Ca2+-dependent mechanism. |
GO:0045862 |
positive regulation of proteolysis |
biological_process |
Any process that activates or increases the frequency, rate or extent of the hydrolysis of a peptide bond or bonds within a protein. |
GO:0097202 |
activation of cysteine-type endopeptidase activity |
biological_process |
Any process that initiates the activity of the inactive enzyme cysteine-type endopeptidase. |
GO:0002934 |
desmosome organization |
biological_process |
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a desmosome. A desmosome is a patch-like intercellular junction found in vertebrate tissues, consisting of parallel zones of two cell membranes, separated by an space of 25-35 nm, and having dense fibrillar plaques in the subjacent cytoplasm. |
GO:0007219 |
Notch signaling pathway |
biological_process |
A series of molecular signals initiated by the binding of an extracellular ligand to the receptor Notch on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription. |
GO:0034113 |
heterotypic cell-cell adhesion |
biological_process |
The attachment of a cell to a cell of a different type via adhesion molecules. |
GO:0072332 |
intrinsic apoptotic signaling pathway by p53 class mediator |
biological_process |
A series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a cell. The pathway is induced by the cell cycle regulator phosphoprotein p53, or an equivalent protein, and ends when the execution phase of apoptosis is triggered. |
GO:0097186 |
amelogenesis |
biological_process |
The process whose specific outcome is the formation of tooth enamel, occurring in two stages: secretory stage and maturation stage. |
GO:0005739 |
mitochondrion |
cellular_component |
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. |
GO:0005794 |
Golgi apparatus |
cellular_component |
A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. |
GO:0005887 |
integral component of plasma membrane |
cellular_component |
The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
