Matriptase-2 (TMPRSS6) is a serine protease with a conserved structure across mammals. Its functions are unknown but high expression in the liver suggests roles in normal and disease states.
Area of Science:
- Biochemistry
- Molecular Biology
- Enzymology
Background:
- Matriptase-2 (TMPRSS6) is a type II transmembrane serine protease.
- It shares structural similarities with matriptase (MT-SP1).
- Its physiological roles remain largely uncharacterized.
Purpose of the Study:
- To provide an overview of matriptase-2.
- To summarize its structural, biochemical, and expression characteristics.
- To discuss potential functions and disease associations.
Main Methods:
- Literature review and data synthesis.
- Structural and biochemical analysis.
- Expression pattern analysis.
Main Results:
- Matriptase-2 possesses a conserved domain structure including CUB and LDL receptor domains.
- Biochemical analysis indicates substrate specificity similar to matriptase.
- High mRNA expression observed in liver and various cancers.
Conclusions:
- Matriptase-2 is a conserved enzyme with potential cell surface-associated roles.
- Further research is needed to elucidate its specific functions in normal physiology and disease.
- Its expression pattern suggests involvement in liver function and cancer progression.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
