Keratin 71 Activators

Chemical activators of Keratin 71 include a variety of compounds that influence the protein's function through different mechanisms. Dimethyl Sulfoxide enhances membrane permeability, which can alter the cellular environment of Keratin 71, influencing its activity by promoting more favorable conditions for its functional state. For instance, by altering membrane dynamics and cellular hydration, Dimethyl Sulfoxide can create a milieu that facilitates the conformational changes necessary for Keratin 71 activation. Retinoic Acid, known to play a role in cellular differentiation, can lead to the activation of Keratin 71 as cells progress through various stages of differentiation where Keratin 71 is involved. Similarly, Calcium Chloride and Magnesium Chloride contribute to the activation of Keratin 71 by affecting the ionic balance within the cell, which can induce structural changes in the protein, leading to its activation.

Furthermore, Zinc Chloride, Copper(II) Sulfate, and Sodium Orthovanadate act as cofactors or inhibitors of enzymes that post-translationally modify proteins such as Keratin 71. Zinc Chloride and Copper(II) Sulfate might participate in enzymatic reactions that attach functional groups to Keratin 71, modifying its activity state. In contrast, Sodium Orthovanadate can inhibit phosphatases, preventing dephosphorylation and thus maintaining Keratin 71 in an active phosphorylated state. Lithium Chloride's inhibition of GSK-3, a kinase involved in protein phosphorylation, can similarly result in a more active form of Keratin 71. Dithiothreitol (DTT) works by reducing disulfide bonds within Keratin 71, which can lead to a conformational shift and subsequent activation of the protein. On the other hand, Hydrogen Peroxide can induce an oxidative stress response that may involve the activation of Keratin 71 as part of the cellular mechanism to manage oxidative stress. Isoproterenol, a beta-adrenergic agonist, raises intracellular cAMP levels, which can modify the phosphorylation pattern of Keratin 71, affecting its activity. Lastly, Urea, through its protein-denaturing properties, can disrupt inhibitory complexes bound to Keratin 71, leading to the liberation and activation of the protein.
