LOC729465 Activators

Forskolin, by stimulating adenylate cyclase, and IBMX, through inhibition of phosphodiesterases, both raise the levels of cyclic nucleotides, cAMP, and cGMP, which are crucial second messengers in cellular signaling. The elevation of these molecules activates protein kinases A and G (PKA and PKG), which can phosphorylate and thus modify the activity of a broad spectrum of proteins. Phorbol esters like PMA are well-known activators of protein kinase C (PKC), which phosphorylates proteins and alters their functions.

Calcium modulators such as Ionomycin, A23187, and Thapsigargin disrupt calcium homeostasis, which is a universal signaling entity, influencing a myriad of calcium-binding proteins and associated kinases and phosphatases. Retinoic Acid and 5-Azacytidine exert their effects at the genomic level, altering gene expression and thereby the synthesis and activity of proteins. Dibutyryl-cAMP serves as a synthetic mimic of cAMP, directly activating PKA, while Sodium Butyrate, by inhibiting histone deacetylases, affects chromatin structure and gene expression. Chloroquine has been found to impact cellular processes such as autophagy, which can have downstream effects on protein activity.
