Heat shock protein Hsp-16.48/Hsp-16.49. unfolded protein binding.
Solver output
hsp-16.48 encodes a small heat shock protein (sHSP) in C. elegans that functions as a molecular chaperone via unfolded protein binding. Small HSPs act as holdases, capturing misfolded or aggregation-prone proteins and preventing their toxic accumulation, thereby maintaining proteostasis. In C. elegans, the hsp-16 family genes are transcriptional targets of the DAF-16/FOXO and HSF-1 transcription factors, both of which are central mediators of the insulin/IGF-1 signaling longevity pathway. Overexpression of hsp-16 family members has been shown to extend lifespan, while their induction is a hallmark of long-lived daf-2 mutants. By suppressing protein aggregation—a key driver of age-related proteotoxicity—this chaperone directly opposes the loss of proteostasis that characterizes aging.
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 hsp-16.48. The mechanistic reasoning is thorough and accurate: it correctly identifies hsp-16.48 as a small heat shock protein acting as a molecular chaperone/holdase, correctly links it to DAF-16/FOXO and HSF-1 transcriptional regulation, correctly notes its role in the insulin/IGF-1 signaling longevity pathway, and correctly identifies proteostasis maintenance as the key mechanism. The model also correctly notes that overexpression of hsp-16 family members extends lifespan and that their induction is a hallmark of long-lived daf-2 mutants. The confidence level of 0.82 is appropriate given the well-established biology of this gene family.
