Cathepsin D (UniProt: P07339; also known as EC:3.4.23.5, Pro-CTSD) is encoded by the CTSD (also known as CPSD) gene (Gene ID: 1509) in human. Cathepsin D is a ubiquitously expressed, major lysosomal and secreted aspartic protease that is synthesized as a pro-cathepsin with a signal peptide (aa 1-20) and an activation peptide (aa 21-64) that are subsequently cleaved off. Following the removal of the signal peptide within the endoplasmic reticulum, the inactive pro-cathepsin D is glycosylated and transported to the Golgi compartment, where the mannose residues are phosphorylated for targeting to lysosomes via the mannose-6-phosphate pathway. An acidic environment is important for proteolytic processing and maturation of cathepsin D. Once in the endosomes, the phosphate groups and the activation peptide (pro-peptide) are removed to generate an active intermediate. In the lysosomal compartment, this single-chain intermediate is further processed into a double-chain mature form consisting of an N-terminal light chain (aa 65-162) and a C-terminal heavy chain (aa 169-412) that remain associated in a non-covalent manner. Cathepsin D plays an active role in intracellular protein breakdown. It is reported to be involved in the degradation of various substrates, including -synuclein, amyloid precursor protein (APP) and tau, all of which tend to aggregate and lead to neurodegenerative diseases if not efficiently degraded. Increased tissue expression of cathepsin D has been correlated with higher incidence of cancer and poor outcome in a number of cancers. Overexpression of cathepsin D in human breast cancers is associated with higher risk of relapse and metastasis. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions

Clone 1D16 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects pro-cathepsin D. It targets an epitope within 25 amino acids from the N-terminal, propeptide region.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Preparation Note

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
