Cathepsin D Antibody (PA1-26253) in WB
Western blot was performed using Anti-Cathepsin D Polyclonal Antibody (Product # PA1-26253) and a 48 kDa band corresponding to Preprocathepsin D along with a 30 kDa band that corresponds to Cathepsin D heavy chain was observed across cell lines tested. Whole cell extracts (30 µg lysate) of MCF7 (Lane 1), Hep G2 (Lane 2), PANC-1 (Lane 3) and SK-BR-3 (Lane 4) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot®... View More

Target Information
Cathepsin D is a gene located on chromosome 11p15.5 that encodes a lysosomal aspartic protease involved in the degradation of proteins. This enzyme is widely expressed in various tissues but is particularly abundant in the liver, kidneys, and brain, where it plays a crucial role in intracellular protein catabolism and turnover. Cathepsin D is synthesized as an inactive precursor, procathepsin D, which is activated in the acidic environment of lysosomes. Beyond its fundamental role in protein degradation, Cathepsin D has been implicated in several physiological and pathological processes, including apoptosis, hormone processing, and antigen presentation. Dysregulation of Cathepsin D expression or activity is associated with various diseases, such as neurodegenerative disorders, cancer, and cardiovascular diseases. In the context of cancer, Cathepsin D overexpression has been linked to tumor progression and metastasis, making it a potential biomarker and therapeutic target. Research continues to explore its diverse biological functions and therapeutic implications in various medical conditions.
