Chemical activators of BRICHOS domain containing 5 can influence the protein's activity through various cellular signaling pathways. Calcium Ionophore A23187, for instance, facilitates the influx of calcium ions into the cell, thereby amplifying intracellular calcium signaling. This increase in calcium concentration can be pivotal in triggering calcium-dependent kinases, which, in turn, phosphorylate and enhance the functional activity of BRICHOS domain containing 5. Similarly, Ionomycin, another calcium ionophore, elevates cytosolic calcium levels, potentially leading to the activation of calcium-dependent kinases that target and activate BRICHOS domain containing 5. BAY K8644, functioning as a L-type calcium channel agonist, also contributes to the rise in intracellular calcium, which is a critical factor for the activation of kinases that can phosphorylate BRICHOS domain containing 5.

The protein kinase C (PKC) pathway is another conduit through which BRICHOS domain containing 5 can be activated. Phorbol 12-myristate 13-acetate (PMA) directly activates PKC, which may then phosphorylate BRICHOS domain containing 5. Sphingosine-1-phosphate, which activates its receptors, can initiate downstream signaling that activates PKC, again leading to the phosphorylation and activation of BRICHOS domain containing 5. In addition, Forskolin, by activating adenylate cyclase, boosts cAMP levels, which in turn can activate protein kinase A (PKA). PKA then has the capacity to phosphorylate BRICHOS domain containing 5, resulting in its activation. Dibutyryl-cAMP, a cAMP analog, engages a similar cAMP-PKA signaling pathway leading to the activation of BRICHOS domain containing 5. Isoproterenol, through the stimulation of β-adrenergic receptors, also increases adenylate cyclase activity and cAMP levels, fostering an environment conducive to PKA activation and subsequent phosphorylation of BRICHOS domain containing 5. Moreover, Anisomycin, by activating stress-activated protein kinases such as JNK, can lead to the phosphorylation and activation of BRICHOS domain containing 5. Thapsigargin operates through a different mechanism, causing the inhibition of the SERCA pump and a resulting rise in cytosolic calcium, which activates calcium-dependent kinases that phosphorylate BRICHOS domain containing 5. Phosphatidic acid, acting as a lipid second messenger, can activate mTOR signaling pathways, which may promote the phosphorylation and activation of BRICHOS domain containing 5. Lastly, the binding of Epidermal Growth Factor (EGF) to its receptor sets off a cascade of kinase activations that can culminate in the phosphorylation and activation of BRICHOS domain containing 5, integrating it into the broad network of cell signaling.
