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 will serve as lifting pads for the electrical contacts.

These bunks also serve as a fence, so part of the additional cost must be attributed to the fence.

These changes represent, in effect, a shift from ( 1 ) an administrative compilation of data obtained through procedures designed primarily to serve political and economic objectives to ( 2 ) a systematic sampling census of the whole African population.

`` These actions should serve to protect in fact and in effect the court's wards from undue costs and its appointed and elected servants from unmeritorious criticisms '', the jury said.

These men -- for the most part educated in our `` best '' New England colleges, well established financially and socially in the community -- under kindly but insistent probing, reveal little or no objective or explicit criteria or data for their generalizations about the interests and attitudes of the people they claim to serve, or about the public responses that actually follow their occasional breach of a `` client-service relationship ''.

These " abbots " are appointed by the brothers and sisters of Redwall to serve as a superior and provide paternal care, much like real abbots.

These papal bulls came to serve as a justification for the subsequent era of slave trade and European colonialism.

These numbers provide valuable services to the customers they serve ; it is, therefore, inadvisable to misuse them.

These conventions allow some operators in both languages to serve both as predicates ( answering a boolean-valued question ) and as returning a useful value for further computation, but in Scheme the value '() which is equivalent to NIL in Common Lisp evaluates to true in a boolean expression.

These higher speeds better serve the longer distances involved.

These myths often depict creation as the result of a sexual union, and serve as genealogical record of the deities born from it.

These controls serve the purpose to maintain the system's quality attributes, among them confidentiality, integrity, availability, accountability and assurance.

These films leave the impression that Clark Kent is really a secret identity that is used to enable Superman to serve humanity better, rather than just a role to help him assimilate into the human community.

These are trained to serve out of fear until they obtain sufficient knowledge to serve out of love.

These provide both a means for cruising sailors to stay in touch with families and loved ones and equally serve to propagate the lifestyle and share information between cruisers and ' want-to-be ' cruisers.

These two " Official Declarations " are not revelations, but they serve as the formal announcements that a revelation was received.

These formulas can even serve as the definition of the trigonometric functions for complex arguments x.

These influences serve to reinforce the conclusion that the Book of Exodus originated in the exiled Jewish community of 6th-century Babylon, but not all the sources are Mesopotamian: the story of Moses's flight to Midian following the murder of the Egyptian overseer may draw on the Egyptian Tale of Sinuhe.

These ethnic distinctions and subdivisions serve to define each ethnicity's unique cultural identity.

These fossils serve as a reminder that taxonomic divisions are human constructs that have been imposed in hindsight on a continuum of variation.

These trains usually connect larger agglomerations to the suburban areas, although in the case of the Rhein-Ruhr S-Bahn these also serve as a method of interurban transport between large cities.

These tunnels serve as both a hiding place for the characters and as a place of secrets.

These offices serve as the official representative of the Government of the Hong Kong SAR in these countries.

These used three crankshafts to serve three banks of double-ended cylinders arranged in an equilateral triangle with the crankshafts at the corners.
