2210415I11Rik Activators

Chemical activators of coiled-coil domain containing 73 can initiate a cascade of intracellular events leading to the protein's activation through phosphorylation. Phorbol 12-myristate 13-acetate (PMA) and 1,2-Dioctanoyl-sn-glycerol are both known to activate protein kinase C (PKC), a family of enzymes that play a central role in the regulation of cellular functions. Once activated, PKC can phosphorylate coiled-coil domain containing 73, altering its activity. Similarly, forskolin raises the levels of intracellular cAMP, subsequently activating protein kinase A (PKA), which can also target and phosphorylate coiled-coil domain containing 73 to modulate its function. Ionomycin, by increasing intracellular calcium concentrations, can activate calcium/calmodulin-dependent protein kinases (CaMKs) that may directly phosphorylate coiled-coil domain containing 73.

In parallel, growth factors such as Epidermal Growth Factor (EGF) and Vascular Endothelial Growth Factor (VEGF) initiate their signaling pathways through the activation of their respective receptors. EGF triggers the MAPK/ERK pathway, while VEGF activates the PI3K/Akt pathway, both of which can lead to the phosphorylation and consequent activation of coiled-coil domain containing 73. Anisomycin operates through the activation of the JNK pathway, a stress-activated protein kinase pathway that can phosphorylate a variety of proteins, possibly including coiled-coil domain containing 73. Hydrogen peroxide (H2O2) serves as a signaling molecule that activates kinases capable of modifying the phosphorylation state of numerous proteins. Insulin engages the PI3K/Akt signaling pathway upon binding to its receptor, which is known for its role in the regulation of various proteins through phosphorylation. Sodium Fluoride activates G-proteins, which in turn can activate multiple signaling pathways, potentially leading to the phosphorylation of coiled-coil domain containing 73. Isoproterenol, through its action on beta-adrenergic receptors, leads to an increase in cAMP and activates PKA, which then can phosphorylate coiled-coil domain containing 73. Lastly, the calcium ionophore A23187 elevates intracellular calcium levels, thereby activating calcium-dependent kinases that can phosphorylate and modulate the activity of coiled-coil domain containing 73.
