FASTKD2 Activators

Chemical activators of Fas-activated serine/threonine kinase domain 2 (FASTKD2) can engage multiple cellular pathways to modulate its activity. The compound AICAR, for instance, can activate AMP-activated protein kinase (AMPK), a key regulator of energy balance within the cell. The activation of AMPK by AICAR can lead to enhanced mitochondrial activity, which is a context where FASTKD2 operates. Similarly, metformin, berberine, and quercetin, all known to activate AMPK, can also support mitochondrial function and thereby increase the activity of FASTKD2. The activation of AMPK signals a boost in mitochondrial biogenesis and function, creating an environment that fosters the activity of mitochondrial proteins, including FASTKD2.

On another front, compounds like SRT1720 and resveratrol activate SIRT1, a member of the sirtuin family of proteins that is known to influence the aging process by affecting cellular metabolism and mitochondrial biogenesis. The activation of SIRT1 by these compounds leads to the deacetylation and activation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), further promoting the biogenesis of mitochondria. This, in turn, can enhance the function of mitochondrial proteins such as FASTKD2. Moreover, PPAR agonists like pioglitazone and bezafibrate activate peroxisome proliferator-activated receptors, which are nuclear receptors that play a pivotal role in the regulation of mitochondrial genes and can support the function of FASTKD2. Leucine, an amino acid known to activate the mTOR pathway, can increase protein synthesis and mitochondrial biogenesis, which may also support the activity of FASTKD2. Lastly, nicotinamide riboside, as a precursor of NAD+, can boost the levels of this crucial cofactor, thereby activating SIRT1 and supporting the function of FASTKD2.
