  2. Allosteric modulator - Wikipedia

    en.wikipedia.org/wiki/Allosteric_modulator

    The site that an allosteric modulator binds to (i.e., an allosteric site) is not the same one to which an endogenous agonist of the receptor would bind (i.e., an orthosteric site). Modulators and agonists can both be called receptor ligands. [2] Allosteric modulators can be 1 of 3 types either: positive, negative or neutral.

  3. Allosteric regulation - Wikipedia

    en.wikipedia.org/wiki/Allosteric_regulation

    Allosteric regulation of an enzyme. In the fields of biochemistry and pharmacology an allosteric regulator (or allosteric modulator) is a substance that binds to a site on an enzyme or receptor distinct from the active site, resulting in a conformational change that alters the protein's activity, either enhancing or inhibiting its function.

  5. AMPA receptor positive allosteric modulator - Wikipedia

    en.wikipedia.org/wiki/AMPA_receptor_positive...

    CX-516, one of the earliest and a prototypical AMPAR PAM.It is a low-impact AMPAR PAM. Tulrampator (S-47445, CX-1632), a newer and high-impact AMPAR PAM.. AMPA receptor positive allosteric modulators are positive allosteric modulators (PAMs) of the AMPA receptor (AMPR), a type of ionotropic glutamate receptor which mediates most fast synaptic neurotransmission in the central nervous system.

  6. Allosteric enzyme - Wikipedia

    en.wikipedia.org/wiki/Allosteric_enzyme

    Allosteric enzymes need not be oligomers as previously thought, [1] and in fact many systems have demonstrated allostery within single enzymes. [2] In biochemistry, allosteric regulation (or allosteric control) is the regulation of a protein by binding an effector molecule at a site other than the enzyme's active site.

  7. Receptor modulator - Wikipedia

    en.wikipedia.org/wiki/Receptor_modulator

    A receptor modulator, or receptor ligand, is a general term for a substance, endogenous or exogenous, that binds to and regulates the activity of chemical receptors.They are ligands that can act on different parts of receptors and regulate activity in a positive, negative, or neutral direction with varying degrees of efficacy.

  8. GABA receptor agonist - Wikipedia

    en.wikipedia.org/wiki/GABA_receptor_agonist

    Positive allosteric modulators work by increasing the frequency with which the chloride channel opens when an agonist binds to its own site on the GABA receptor. The resulting increase in the concentration of Cl− ions in the postsynaptic neuron immediately hyperpolarizes this neuron, making it less excitable and thus inhibiting the ...

  9. Cooperativity - Wikipedia

    en.wikipedia.org/wiki/Cooperativity

    A much more general and useful definition of positive cooperativity is: A process involving multiple identical incremental steps, in which intermediate states are statistically underrepresented relative to a hypothetical standard system (null hypothesis) where the steps occur independently of each other.
