Solver output
dkf-2 encodes a diacylglycerol (DAG)-dependent serine/threonine kinase, the C. elegans ortholog of mammalian Protein Kinase D (PKD). DAG-dependent kinases are activated downstream of phospholipase C and DAG signaling, which intersects with insulin/IGF-1 and nutrient-sensing pathways. PKD/DKF-2 activity promotes DAF-16/FOXO nuclear exclusion and suppresses stress-response programs, thereby opposing longevity-promoting transcriptional outputs. In C. elegans, elevated DAG signaling (e.g., via loss of diacylglycerol kinase dgk-1) shortens lifespan, and DKF-2 is a key effector of this pro-aging DAG signal. By phosphorylating substrates that dampen stress resistance and proteostasis responses, DKF-2 activity is expected to shorten lifespan, making it anti-longevity in its normal function.
GenAge curators classify each gene's normal function as promoting (Pro-Longevity) or opposing (Anti-Longevity) longevity, based on synthesis across studies. Loss-of-function effects can vary from this depending on the manipulation.
Advisor judgment
The model correctly predicted dkf-2 as anti_longevity with reasonable confidence (0.68). The mechanistic reasoning is well-grounded: dkf-2 is indeed the C. elegans ortholog of PKD (Protein Kinase D), it is DAG-dependent, and its activity promotes aging by suppressing stress-response programs and DAF-16/FOXO activity. The connection to DAG signaling and its role as a pro-aging effector is accurate. The model correctly identifies that DKF-2 activity shortens lifespan. The reasoning is solid and mechanistically plausible, though the specific claim about DAF-16 nuclear exclusion via DKF-2 phosphorylation could be slightly speculative. Overall, this is a well-reasoned correct prediction.
