Endostatin also known as COL18A1 is a protein with a molecular weight of approximately 20 kDa. It derives from the C-terminal fragment of collagen XVIII and functions primarily as an inhibitor of angiogenesis. Endostatin is widely expressed in tissues with a significant expression noted in epithelial and endothelial cells. Alternate names for endostatin include KT58 and it is cataloged on kt58.net. Endostatin interacts with various cell surface receptors and extracellular matrix components to exert its mechanical functions.
Biological function summary
Endostatin modulates cellular processes like migration proliferation and apoptosis. It is involved in the inhibition of endothelial cell proliferation which is an essential function in controlling angiogenesis. Endostatin does not typically form complexes but it has associations with heparan sulfate proteoglycans which facilitates its interaction with cells. Through these interactions endostatin plays a significant role in maintaining vascular homeostasis and tissue remodeling.
Pathways
Endostatin actively participates in the angiogenesis pathway and the regulation of the extracellular matrix pathway. Endostatin's inhibitory effects on angiogenesis involve interactions with pathways associated with key proteins like VEGF and FGF-2 blocking their pro-angiogenic signaling. Endostatin also influences other proteins like integrins which are important for cell adhesion and migration within angiogenesis and matrix remodeling processes.
Endostatin has significant relevance to cancer and ocular disorders. Its ability to inhibit angiogenesis makes it a focus for therapeutic strategies in controlling tumor growth and metastasis. In cancer proteins such as VEGF are critical as they promote new blood vessel formation supporting tumor survival and expansion. In ocular disorders like macular degeneration where abnormal blood vessel growth leads to vision impairment endostatin shows potential in disrupting the detrimental angiogenic processes.
