Short Description: This human HTRA1 kit is a highly sensitive in-vitro chemiluminescent immunoassay for the measurement of trace amounts of analytes.
Storage Instruction: If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual.
Assay Time: 3.5h
Detection: Chemiluminescence
Gene Symbol: HTRA1
Gene ID: 5654
Uniprot ID: HTRA1_HUMAN
Specificity: This kit recognizes Human HTRA1 in samples. No significant cross-reactivity or interference between Human HTRA1 and analogues was observed.
Sample Type: Serum, plasma and other biological fluids
Tissue Specificity Widely expressed, with strongest expression in placenta (at protein level). Secreted by synovial fibroblasts. Up-regulated in osteoarthritis and rheumatoid arthritis synovial fluids and cartilage as compared with non-arthritic (at protein level).
Function 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 IGF-binding 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.
