Disease

[CATD_HUMAN] Defects in CTSD are the cause of neuronal ceroid lipofuscinosis type 10 (CLN10) [MIM:610127]; also known as neuronal ceroid lipofuscinosis due to cathepsin D deficiency. 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.^[1] ^[2] ^[3]

Function

[CATD_HUMAN] Acid protease active in intracellular protein breakdown. Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease.

Publication Abstract from PubMed

The crystal structure of a catalytically inactive form of cathepsin D (CatDhi) has been obtained at pH 7.5. The N-terminal strand relocates by 30 A from its position in the interdomain beta-sheet and inserts into the active site cleft, effectively blocking substrate access. CatDhi has a five-stranded interdomain beta-sheet and resembles Intermediate 3, a hypothetical structure proposed to be transiently formed during proteolytic activation of the proenzyme precursor. Interconversion between active and inactive forms of CatD is reversible and may be regulated by an ionizable switch involving the carboxylate side chains of Glu 5, Glu 180, and Asp 187. Our findings provide a structural basis for the pH-dependent regulation of aspartic proteinase activity and suggest a novel mechanism for pH-dependent modulation of substrate specificity.
