ABHD12B Activators

ABHD12B activators function through various biochemical mechanisms to enhance the activity of this hydrolase enzyme. Activation can occur through modification of intracellular second messenger levels, as seen with compounds that increase cyclic AMP (cAMP) within the cell. Elevated cAMP levels can result in the activation of protein kinases that phosphorylate ABHD12B, leading to enhanced enzyme functionality. Such phosphorylation events are central in the regulation of ABHD12B, as they can alter its conformation and consequently its activity. Additionally, bioactive lipids play a significant role by interacting with receptors that initiate signaling cascades, culminating in the phosphorylation or allosteric modulation of ABHD12B. These lipids may also be metabolized into molecules that directly influence ABHD12B's activation state. Moreover, alterations in intracellular calcium levels can activate calcium-dependent kinases, which can then target ABHD12B for activation through phosphorylation.

Furthermore, the modulation of cellular metabolism and the redox environment by specific cofactors can have an indirect impact on the pathways that lead to ABHD12B activation. For instance, changes in the acylation status of proteins due to the action of sirtuins can affect ABHD12B activity. Similarly, compounds that inhibit protein tyrosine phosphatases or glycogen synthase kinase-3 (GSK-3) can lead to an increase in phosphorylated proteins, creating a favorable environment for the activation of ABHD12B.
