Notes: CLCN7 is a antiporter that transports 2 chloride ions into the lysosome in exchange for pumping one proton out. It helps to maintain ion homoeostasis in the lysosome during acidification.

PN-node mapping records (path + ancestors):
[subtype] Autophagy-Lysosome Pathway|Lysosomal catabolism|Regulation of lysosomal environment|Lysosomal acidification|Miscellaneous function - lysosomal acidification
status=no_mapping scope= GO=[]
rationale: Reviewed as an unknown or residual PN category. The label does not provide a shared GO-mappable biological process, molecular function, or cellular component.
[type] Autophagy-Lysosome Pathway|Lysosomal catabolism|Regulation of lysosomal environment|Lysosomal acidification
status=mapped scope=ok_for_propagation_to_go GO=[GO:0007042 lysosomal lumen acidification]
rationale: This PN group directly names the lysosomal acidification mechanism. Propagation to the GO lysosomal lumen acidification term is an exact mechanistic match.
[group] Autophagy-Lysosome Pathway|Lysosomal catabolism|Regulation of lysosomal environment
status=no_mapping scope= GO=[]
rationale: Reviewed as a broad PN taxonomy container. The descendants mix components, regulators, context labels, and mechanistic leaves, so propagation should come only from narrower curated nodes.
[class] Autophagy-Lysosome Pathway|Lysosomal catabolism
status=no_mapping scope= GO=[]
rationale: Reviewed as a broad lysosomal-degradation container. The subtree includes carbohydrate, lipid, protein, nuclease, phosphatase, sulfatase, and environment-regulation roles, so mapping should occur at the enzyme or process subtype level.
[branch] Autophagy-Lysosome Pathway
status=no_mapping scope= GO=[]
rationale: Reviewed as the top-level PN branch. It is a project taxonomy umbrella rather than a direct GO assertion; all propagation must come from manually curated child nodes.
