Stress-induced protein 1. unfolded protein binding.
Solver output
SIP-1 (Stress-Induced Protein 1) is a co-chaperone that binds unfolded proteins, placing it squarely in the proteostasis network. In C. elegans, maintaining proteostasis is a well-established pro-longevity mechanism; chaperones and co-chaperones that assist in refolding or triaging misfolded proteins help prevent toxic protein aggregation. SIP-1 is the ortholog of mammalian STI1/STIP1/HOP, which bridges HSP70 and HSP90 chaperone complexes, facilitating client protein folding under stress conditions. By binding unfolded proteins and coordinating their handoff to the HSP70/HSP90 machinery, SIP-1 supports the heat-shock response and proteostatic capacity that declines with age. Loss of such co-chaperone activity would be expected to accelerate proteotoxic stress and shorten lifespan, consistent with a pro-longevity role for the normal gene 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 pro_longevity for sip-1. The mechanistic reasoning is sound and well-articulated: SIP-1 as a stress-induced co-chaperone involved in proteostasis, with its ortholog being STI1/HOP bridging HSP70/HSP90. The logic that loss of co-chaperone activity would accelerate proteotoxic stress and shorten lifespan is consistent with a pro-longevity classification. The confidence of 0.72 is reasonable. The reasoning is largely correct though it is somewhat inferred from general knowledge about chaperone biology rather than specific C. elegans sip-1 experimental data, but the conclusion and mechanism are appropriate.
