General description

Cathepsins are normally localized in lysosomes of almost all mammalian cells, but under certain conditions they can be secreted from the cells that take part in local proteolysis. Cathepsin Z is a cysteine protease, predominantly expressed in immune cells including monocytes, macrophages or dendritic cells.
This ELISA antibody pair detects Human Cathepsin Z (CTSZ/Cathepsin X/Cathepsin P)

Application

For research use only. Not for use in diagnostic procedures.
Please refer to the attached Protocolfor details.

Biochem/physiol Actions

Cathepsins are lysosomal proteases that play an important role in the intracellular degradation of exogenous and endogenous proteins, activation of enzyme precursors, and tumor invasion and metastasis. Cathepsin Z is known to be associated with the pathogenesis of cancer and promotes the development and proliferation of tumor cells. Cathepsin Z mediates the process of proliferation, migration, maturation, adhesion, signal transduction and phagocytosis of immune cells.
