These tumor suppressing proteins regulate the cell cycle, but are rendered inactive when bound to an inhibitory protein.

These two inhibitory proteins are partially responsible for HeLa cells immortality by inhibiting apoptosis to occur.

These homologs can inhibit proapoptotic proteins such as BAX and BAK, which are essential for the activation of apoptosis.

These bacteria also secrete proteins that enable the AC-II to enter host cells, where the exogenous AC activity undermines normal cellular processes.

These oxidants can damage cells by starting chemical chain reactions such as lipid peroxidation, or by oxidizing DNA or proteins.

These factors include insulin-like growth factors I and II, transforming growth factor-beta, fibroblast growth factor, platelet-derived growth factor, and bone morphogenetic proteins.

These similarities include the energy carrier adenosine triphosphate ( ATP ), and the fact that all amino acids found in proteins are left-handed.

These methods can be applied to proteins and other large biological molecules, and allow studies of the approach and interaction ( docking ) of potential drug molecules ( e. g. and ).

These proteins can specifically catalyze a single reaction, so that reactions can be controlled very precisely.

These proteins are often concentrated in specialized cells and in cell corners.

These fusion proteins are labeled with compounds such as His-tags, biotin or antigens, which bind to the stationary phase specifically.

These play a dual role of a site of recognition by many proteins and as a sink for torsional stress from RNA polymerase or nucleosome binding.

These receptors may bind attractants or repellents directly or indirectly through interaction with proteins of periplasmatic space.

These fiber types are chemically different, corresponding to proteins, carbohydrates and synthetic polymers, respectively.

These compact structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.

These initiators recruit other proteins to separate the strands and initiate replication forks.

These organisms are now used for several purposes, and are particularly important in producing large amounts of pure human proteins for use in medicine.

These G proteins are made from three subunits, with the G domain located on the largest one ( the α unit ); together with the two smaller subunits ( β and γ units ), they form a tightly associated protein complex.

These G proteins are used in the signal transduction of taste and smell.

These proteins usually have phospholipase C as effector protein.

These G proteins can be activated by thromboxan receptors and thrombin receptors.

These are small monomeric proteins homologous to Ras.

These proteins are homologous to the alpha ( α ) subunit found in heterotrimers, and are in fact monomeric.

These proteins act to accelerate hydrolysis of GTP to GDP and terminate the transduced signal.

These proteins are homologous to the alpha ( α ) subunit found in heterotrimers, but exist as monomers.

These fields frequently overlap, but tend to use different methodologies and techniques.

These warning colours tend to be red or yellow combined with black, with the fire salamander ( Salamandra salamandra ) being an example.

These alcohols are called fusel alcohols or fusel oils in brewing and tend to have a spicy or peppery flavor.

These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle.

These techniques also tend to form the backbone of most undergraduate analytical chemistry educational labs.

These molecules tend to be used as markers and signals, as well as having some other uses.

These persons generally have increased energy and tend to become more active than usual.

These longer chain acids tend to be rather soluble in less-polar solvents such as ethers and alcohols.

These range in diameter from a few tens of meters up to about 300 km, and they range in age from recent times ( e. g. the Sikhote-Alin craters in Russia whose creation were witnessed in 1947 ) to more than two billion years, though most are less than 500 million years old because geological processes tend to obliterate older craters.

These dialects have roots in 17th-century English and African languages ; unlike most native varieties of English, West Indian dialects often tend to be syllable-timed rather than stress-timed.

These crankshafts tend to be very expensive due to the large amount of material that must be removed with lathes and milling machines, the high material cost, and the additional heat treatment required.

These myths tend to emphasize creative forces as animistic in nature rather than sexual, and depict the sacred as the elemental and integral component of the natural world.

These films tend to feature people as products of their environment, and lean towards the avant-garde.

These " politically neutral " groups tend to avoid global conflicts and view the settlement of inter-human conflict as separate from regard for nature-in direct contradiction to the ecology movement and peace movement which have increasingly close links: While Green Parties and Greenpeace, and groups like the ACTivist Magazine for example, regard ecology, biodiversity and an end to non-human extinction as absolutely basic to peace, the local groups may not, and may see a high degree of global competition and conflict as justifiable if it lets them preserve their own local uniqueness.

These Churches do not practice Communion with any other Orthodox jurisdictions nor do they tend to recognize each other.

These forces will be different depending on how often data is used, so that seldom-used data will tend to be on just a few nodes which specialize in providing that data, and frequently used items will be spread widely throughout the network.

These unpaired dipoles ( often called simply " spins " even though they also generally include angular momentum ) tend to align in parallel to an external magnetic field, an effect called paramagnetism.

These movements or styles tend to classify the artists by their relationship to their social and economic contexts, since, in most countries, graffiti art remains illegal in many forms except when using non-permanent paint.

These students are inclined to infer from these inconsistencies that both manuscripts may represent an exercise in forensic falsification, and they tend to locate their place of origin as Rome.

These technological advances and investment allow the primary sector to require less workforce and, this way, developed countries tend to have a smaller percentage of their workforce involved in primary activities, instead having a higher percentage involved in the secondary and tertiary sectors.

These Australians of Irish background did not tend to regard Ireland as their " mother country "-primarily because few had a wish to return to a home they had left in search of a better life.

These interactions tend to align the molecules to increase the attraction ( reducing potential energy ).

These gases tend to be very hazardous.

These minerals tend to be soft, weak, brittle, and water-soluble.

These micronations tend to have a reasonably serious intent, and often involve significant numbers of people interested in recreating the past or simulating political or social processes.
