Anti-Cysteine-rich, Angiogenic Inducer 61 (CYR61)

Cyr61, also known as IGFBP-10 and CCN1, is a 50kD secreted matrix- and cell-associated glycoprotein that regulates the growth and adhesion of vascular endothelial cells, fibroblasts, and monocytes. Cyr61 interacts with cells that express integrins aVB3, aVB5, aMB2, and a6B1. Cyr61 is cleaved by plasmin within its VWF domain which generates an N-terminal fragment that is not associated with the matrix but retains the ability to induce endothelial cell migration. Cyr61 induces VEGF upregulation, angiogenesis, and tumorigenesis. Between amino acids 176-281, mouse Cyr61 shares 87% and 97% aa sequence identity with human and rat Cyr61, respectively. Applications: Suitable for use in Direct ELISA, Immunohistochemistry and Western Blot. Other applications not tested. Recommended Dilutions: Direct ELISA: 0.5-1ug/ml.
