功能
Acid protease active in intracellular protein breakdown. Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease. -
疾病相关
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. -

Belongs to the peptidase A1 family. -

Predicted band size: 44 kDa
Observed band size: 46 kDa why is the actual band size different from the predicted?Lanes 1 - 4: Merged signal (red and green). Green - ab134169 observed at 46 kDa. Red - loading control, ab7291 (mouse anti-tubulin), observed at 50 kDa.
ab134169 was shown to recognize in wild-type A431 cells as signal was lost at the expected MW in CTSD knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and CTSD knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% NF Milk. Ab134169 and ab7291 (Mouse anti-tubulin loading control) were incubated overnight at 4°C at 1/2000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

Intracellular Flow Cytometry analysis of A431 (human epidermoid carcinoma) cells labeling proCathepsin D with purified ab134169 at 1/100 dilution (10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488) (1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-proCathepsin D antibody [EPR3054] (ab134169)
Immunohistochemical staining of paraffin embedded human breast carcinoma with purified ab134169 at a working dilution of 1 in 50. The secondary antibody used is a HRP polymer for rabbit IgG. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

Immunofluorescence staining of MCF7 cells with purified ab134169 at a working dilution of 1 in 50, counter-stained with DAPI. The secondary antibody was Alexa Fluor® 488 goat anti rabbit (ab150077), used at a dilution of 1 in 500. The cells were fixed in 4% PFA and permeabilized using 0.1% Triton X 100. The negative control is shown in bottom right hand panel - for the negative control, purified ab134169 was used at a dilution of 1/200 followed by an Alexa Fluor® 594 goat anti-mouse antibody at a dilution of 1/500.
