General description
Serine protease 21 (PRSS21) is localized to premeiotic testicular germ cells. The gene encoding this protein is present on the short arm of chromosome 16p13.3. It consists of an N-terminal signal sequence of 27 amino acids, a 251 amino-acid catalytic domain with trypsin-like specificity and a C-terminal hydrophobic region which acts as a membrane anchor.

Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
Serine protease 21 (PRSS21) functions as a tumor suppressor for testicular cancer. It has been shown that the trypsin-like protease activity of PRSS21 is essential for the process of sperm penetration through the cumulus matrix and zona pellucida of the oocyte in vitro. Hence this trypsin-like activity is important for fertilization in vitro but not necessarily in vivo. PRSS21 also contributes to the epididymal sperm maturation and the ability of the sperms to fertilize the oocyte.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

An estimated 25%-40% of infertile men have idiopathic infertility associated with deficient sperm numbers and quality. Here, we identify the membrane-anchored serine protease PRSS21, also known as testisin, to be a novel proteolytic factor that directs epididymal sperm cell maturation

Although sperm serine protease and proteasome have long been believed to play an important role in the fertilization process, the molecular mechanism is still controversial. In this study, we have produced double-knockout mice lacking two sperm serine proteases, ACR and
