Chemical activators of FAM153B can initiate a cascade of intracellular events leading to its phosphorylation and subsequent activation. Forskolin, a diterpene found in the Indian Coleus plant, directly stimulates adenylate cyclase, thereby increasing intracellular levels of cAMP. This elevation in cAMP can activate protein kinase A (PKA), a key regulator of phosphorylation for various proteins, which in turn can target FAM153B for phosphorylation. Similarly, 8-Bromo-cAMP and Dibutyryl-cAMP, both analogs of cAMP, permeate cellular membranes and engage PKA to phosphorylate target proteins, including FAM153B. The activation of PKA through these cAMP analogs ensures that FAM153B is modified appropriately within the signaling pathways.
Other activators function by manipulating intracellular calcium levels, which is also crucial for protein phosphorylation. Compounds such as Ionomycin and A23187 (Calcimycin) act as calcium ionophores, increasing the cytosolic concentration of calcium, which can activate calmodulin-dependent kinase (CaMK). This kinase can phosphorylate FAM153B as part of its downstream signaling. Thapsigargin, by inhibiting the sarco/endoplasmic reticulum Ca2+ ATPase (SERCA), causes a similar rise in cytosolic calcium, indirectly promoting the activation of FAM153B. In addition, BAY K8644, which acts as an L-type calcium channel agonist, leads to an influx of calcium, potentially resulting in the activation of FAM153B through calcium-dependent signaling pathways. The synthetic DAG analog 1,2-Dioctanoyl-sn-glycerol (DiC8) activates protein kinase C (PKC), which is implicated in phosphorylating proteins including FAM153B. Furthermore, Phorbol 12-myristate 13-acetate (PMA) is a known PKC activator, thereby contributing to the phosphorylation landscape of FAM153B. Lastly, inhibitors of protein phosphatases such as Calyculin A and Okadaic Acid prevent dephosphorylation, maintaining FAM153B in a phosphorylated state by inhibiting phosphatases PP1 and PP2A. This mechanism ensures that once FAM153B has been phosphorylated, it remains active for a prolonged period.
