Na(+)/H(+) exchange regulatory cofactor-like protein nrfl-1. protein binding. protein-membrane adaptor activity.
Solver output
nrfl-1 encodes a Na(+)/H(+) exchange regulatory cofactor-like protein with protein binding and protein-membrane adaptor activity. NHE regulatory factors (NHERFs) typically scaffold and regulate Na+/H+ exchangers (NHEs) at the plasma membrane, influencing intracellular pH homeostasis and ion transport. While NHE activity can intersect with nutrient sensing and cellular stress responses, the specific downstream longevity-relevant pathway in C. elegans is not clearly established from these annotations alone. The protein-membrane adaptor role suggests involvement in signal transduction scaffolding, but without clearer links to known pro- or anti-longevity pathways (e.g., insulin/IGF-1, TOR, or mitochondrial function), a directional prediction is not well-supported.
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" with low confidence (0.35), while the ground truth is "anti_longevity." The model failed to make a directional prediction. The reasoning about NHE regulatory factors and pH homeostasis is plausible but doesn't connect to the actual anti-longevity mechanism. The model appropriately acknowledged uncertainty given limited annotations, but ultimately got the answer wrong. The mechanism class of "altered_intercellular_communication" seems speculative and not well-supported by the gene's known functions.
