Synaptosomal-associated protein. SNAP receptor activity.
Solver output
ric-4 encodes a synaptosomal-associated protein (SNAP-25 homolog) with SNARE receptor (SNAP receptor) activity, which mediates vesicle fusion at synapses and is essential for neurotransmitter release. While neuronal signaling is critical for neuroendocrine regulation of lifespan in C. elegans (e.g., insulin/IGF-1 signaling from neurons), the SNARE machinery itself is broadly required for synaptic vesicle exocytosis across many neurotransmitter systems with opposing effects on longevity. Loss of specific neurotransmitter signals (e.g., reduced insulin-like peptide secretion) can extend lifespan, while disruption of others (e.g., serotonin or acetylcholine) may shorten it. Because ric-4/SNAP-25 is a general component of the vesicle fusion machinery rather than a pathway-specific regulator, its net effect on longevity cannot be confidently assigned without knowing which neurosecretory circuits are most affected.
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 predicted "unclear" while the ground truth is "anti_longevity." The model's reasoning about SNARE machinery being broadly required and having opposing effects on longevity is plausible but ultimately led to an incorrect conclusion. The model correctly identified the synaptic vesicle exocytosis function and neuroendocrine regulation as relevant pathways, but failed to commit to a direction. The ground truth indicates ric-4 is anti-longevity, meaning its loss likely extends lifespan (consistent with reduced insulin-like peptide secretion from neurons), which the model actually mentioned as a possibility but dismissed due to uncertainty about which circuits are most affected. The model's uncertainty was not well-calibrated given that the dominant role of SNAP-25/ric-4 in neuronal insulin-like peptide secretion (which promotes aging via DAF-2) could have been reasoned toward an anti-longevity classification. The mechanism class of "altered_intercellular_communication" is partially relevant but not precisely correct for the anti-longevity mechanism.
