Serine protease with a variety of targets, including extracellular matrix proteins such as fibronectin.
HTRA1-generated fibronectin fragments further induce synovial cells to up-regulate MMP1 and MMP3 production.
May also degrade proteoglycans, such as aggrecan, decorin and fibromodulin.
Through cleavage of proteoglycans, may release soluble FGF-glycosaminoglycan complexes that promote the range and intensity of FGF signals in the extracellular space.
Regulates the availability of insulin-like growth factors (IGFs) by cleaving IGFbinding proteins.
Inhibits signaling mediated by TGF-beta family members.
This activity requires the integrity of the catalytic site, although it is unclear whether TGF-beta proteins are themselves degraded.
By acting on TGF-beta signaling,may regulate many physiological processes, including retinal angiogenesis and neuronal survival and maturation during development.
Intracellularly, degrades TSC2, leading to the activation of TSC2 downstream targets.
Applications:Suitable for use in ELISA, Immunohistochemistry and Immunofluorescence.
