Product Usage Information

Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

CYR61 Antibody recognizes endogenous levels of total CYR61 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro171 of human CYR61 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Cysteine-rich protein 61 (CYR61, CCN1) is a secreted, matrix-associated protein belonging to the CCN family, a protein group characterized primarily by its high cysteine content (1). CYR61 regulates diverse cellular events including cell proliferation, differentiation, angiogenesis, and extracellular matrix formation. Research studies have implicated CYR61 in the development or progression of various cancers, including breast, prostate, lung, and hepatocellular carcinoma (1-4). Notably, its role in promoting cancer progression appears to be context-dependent. For example, investigators have shown that overexpression of CYR61 was positively associated with invasiveness of breast cancer cell lines (2), whereas in primary prostate tumors, expression levels were inversely correlated with tumor aggressiveness (3). In additional research studies of hepatocellular carcinoma, where CYR61 expression was positively associated with cancer progression, CYR61 was shown to be transcriptionally regulated by the Wnt/β-catenin signaling pathway (1).
