RAB-10 is a Rab GTPase that cycles between GTP- and GDP-bound states to regulate vesicular trafficking, particularly in recycling endosome pathways and basolateral membrane trafficking. In C. elegans, RAB-10 has been shown to mediate insulin/IGF-1 receptor (DAF-2) trafficking and recycling at the plasma membrane; loss of rab-10 reduces surface DAF-2 levels, thereby dampening PI3K-AKT signaling and promoting nuclear localization of the FOXO transcription factor DAF-16, which extends lifespan. By facilitating DAF-2 receptor recycling, RAB-10 normally sustains pro-aging insulin/IGF-1 signaling, meaning its normal function is anti-longevity in effect — however, the gene's role in maintaining proper vesicular trafficking and intercellular communication is broadly important. The myosin V binding and ankyrin repeat binding activities support its role in cytoskeletal-dependent vesicle transport. Because RAB-10's primary documented role in aging contexts is sustaining DAF-2/insulin receptor surface availability and thus suppressing DAF-16/FOXO, its normal function opposes longevity by promoting the pro-aging insulin signaling axis.

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.

Notes

The model predicted "pro_longevity" but the ground truth is "anti_longevity." Interestingly, the model's reasoning actually arrives at the correct mechanistic conclusion (RAB-10 sustains pro-aging insulin signaling, so its normal function opposes longevity = anti_longevity), but then contradicts itself by outputting "pro_longevity" as the final answer. The reasoning explicitly states "its normal function opposes longevity by promoting the pro-aging insulin signaling axis," which aligns with anti_longevity, yet the model selected the wrong label. This is a case of internally inconsistent reasoning leading to a wrong final answer. The mechanism described (DAF-2 receptor recycling via RAB-10) is plausible but not well-established in the literature as the primary aging mechanism for rab-10 in C. elegans. The model appears confused between the effect of the gene's activity (anti-longevity) and the effect of its loss-of-function (pro-longevity), ultimately selecting the wrong category despite partially correct reasoning.
