Polymorphism: The Val-58 allele is significantly overrepresented in demented patients (11.8%) compared with non-demented controls (4.9%). Carriers of the Val-58 allele have a 3.1-fold increased risk for developing AD than non-carriers.
Active Site:ACT_SITE 97 97 {ECO:0000255|PROSITE-ProRule:PRU10094, ECO:0000269|PubMed:8393577}.; ACT_SITE 295 295 {ECO:0000255|PROSITE-ProRule:PRU10094, ECO:0000269|PubMed:8393577}.
Catalytic Activity: Reaction=Specificity similar to, but narrower than, that of pepsin A. Does not cleave the 4-Gln-|-His-5 bond in B chain of insulin.; EC=;
Function [CC]:Acid protease active in intracellular protein breakdown. Plays a role in APP processing following cleavage and activation by ADAM30 which leads to APP degradation (PubMed:27333034). Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease. {ECO:0000269|PubMed:27333034}.
Tissue Specificity:Expressed in the aorta extracellular space (at protein level) (PubMed:20551380). Expressed in liver (at protein level) (PubMed:1426530). {ECO:0000269|PubMed:1426530, ECO:0000269|PubMed:20551380}.
Disease:Ceroid lipofuscinosis, neuronal, 10 (CLN10) [MIM:610127]: A form of neuronal ceroid lipofuscinosis with onset at birth or early childhood. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. {ECO:0000269|PubMed:16670177, ECO:0000269|PubMed:16685649, ECO:0000269|PubMed:21990111}. Note=The disease is caused by mutations affecting the gene represented in this entry.
