Target data

Function

Exhibits trypsin-like activity as defined by cleavage of synthetic substrates with Arg or Lys as the P1 site (PubMed:10373424). Involved in the terminal differentiation of keratinocytes through prostasin (PRSS8) activation and filaggrin (FLG) processing (PubMed:18843291). Proteolytically cleaves and therefore activates TMPRSS13 (PubMed:28710277).

Notes

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

Activity summary

ST14 also known as matriptase is a serine protease with a molecular mass of about 92 kDa. It exists as a single-chain zymogen and activates through cleavage to form a two-chain form. Matriptase resides on the surface of epithelial cells and shows high expression in several tissues such as the epidermis prostate and gastrointestinal tract. This protease plays a part in tissue homeostasis by initiating proteolytic cascades that modify the extracellular matrix and influence cellular processes.

Biological function summary

Matriptase regulates proteolytic activation events in the extracellular environment. It instigates cascades that activate specific growth factors and proteases playing a role in cell proliferation and migration. Matriptase forms a complex with hepatocyte growth factor activator inhibitor-1 (HAI-1) which modulates its activity. The balance between matriptase and its inhibitors is important for controlling epithelial cell dynamics and maintaining a healthy cellular environment.

Pathways

Matriptase contributes to key signaling pathways like the epidermal growth factor receptor (EGFR) pathway and the plasminogen activation pathway. Within the EGFR signaling matriptase activates growth factors that influence cell proliferation and survival. It also intersects with proteins like epithelial growth factor receptor and plasminogen which are significant for cellular functions and homeostasis. These pathways are important for maintaining normal tissue function and responding to cellular stress.

Associated diseases and disorders

Deregulation of matriptase is linked to conditions like cancer and ichthyosis. Matriptase overexpression or aberrant activity often relates to tumor progression and cancer metastasis particularly in breast and prostate cancer. Dysregulation also associates with the skin disorder ichthyosis due to imbalance with its inhibitor HAI-1 leading to defective epidermal permeability. Understanding matriptase's role in these diseases helps in designing therapeutic strategies and targeting the protease with specific inhibitors.
