CATB Antibody (Center)

Affinity Purified Rabbit Polyclonal Antibody (Pab)

     
  • WB - CATB Antibody (Center) AP7367C
    Western blot analysis of CATB Antibody (Center) (Cat.# AP7367c) in Y79 cell line lysates (35ug/lane). CATB (arrow) was detected using the purified Pab.
    detail
  • IHC-P - CATB Antibody (Center) AP7367C
    Formalin-fixed and paraffin-embedded human hepatocarcinoma with CATB Antibody (Center), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.
    detail
  • FC - CATB Antibody (Center) AP7367C
    Flow cytometric analysis of HepG2 cells using CATB Antibody (Center)(bottom histogram) compared to a negative control cell (top histogram). FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.

Protein Information
Name CTSB
Synonyms CPSB
Function Thiol protease which is believed to participate in intracellular degradation and turnover of proteins (PubMed:12220505). Cleaves matrix extracellular phosphoglycoprotein MEPE (PubMed:12220505). Involved in the solubilization of cross-linked TG/thyroglobulin in the thyroid follicle lumen (By similarity). Has also been implicated in tumor invasion and metastasis (PubMed:3972105).
Cellular Location Lysosome. Melanosome. Secreted, extracellular space {ECO:0000250|UniProtKB:A1E295}. Apical cell membrane {ECO:0000250|UniProtKB:P10605}; Peripheral membrane protein {ECO:0000250|UniProtKB:P10605}; Extracellular side {ECO:0000250|UniProtKB:P10605}. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV (PubMed:17081065) Localizes to the lumen of thyroid follicles and to the apical membrane of thyroid epithelial cells (By similarity) {ECO:0000250|UniProtKB:P10605, ECO:0000269|PubMed:17081065}
Tissue Location Expressed in the stratum spinosum of the epidermis. Weak expression is detected in the stratum granulosum

Background

The protein CATB is a lysosomal cysteine proteinase composed of a dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. It is also known as amyloid precursor protein secretase and is involved in the proteolytic processing of amyloid precursor protein (APP). Incomplete proteolytic processing of APP has been suggested to be a causative factor in Alzheimer disease, the most common cause of dementia. Overexpression of the protein, which is a member of the peptidase C1 family, has been associated with esophageal adenocarcinoma and other tumors.
