Cyr61, also known as CCN1, is a 40 - 45 kDa matricellular glycoprotein that plays an important role in cellular adhesion and migration (1). Cyr61 consists of an IGFBP domain, a VWF type C domain, a TSP type I domain, and a cysteine knot domain (2). Mature human Cyr61 shares 93% amino acid sequence identity with mouse and rat Cyr61. It is widely expressed during development and in adult tissues (2, 3). Cyr61 associates with the extracellular matrix (ECM) and with many cell surface molecules including Integrins alpha V beta 3, alpha V beta 5, alpha M beta 2, and alpha 6 beta 1, Syndecan-4, and heparan sulfate proteoglycans (1, 3). Cyr61 mediates the adhesion and migration of multiple cell types and also promotes vascular endothelial cell tubule formation (4 - 6). Plasmin cleavage of ECM-bound Cyr61 releases a 28 kDa N-terminal fragment which retains the ability to promote endothelial cell migration (7). Cyr61 exhibits both tumorigenic and tumor suppressor properties. It is upregulated and promotes tumorigenesis, angiogenesis, and metastasis in breast, renal, gastric, squamous cell, and colorectal carcinomas as well as in glioma (8 - 12). In contrast, when downregulated, it suppresses tumor growth in endometrial, hepatic, and non-small cell lung cancers (8, 13, 14). Cyr61 is also upregulated in injured skin and bone where it induces the expression of growth factors, cytokines, proteases, and integrins involved in wound repair (15, 16).

Detection of Cyr61/CCN1 by Flow Cytometry
Cyr61 displays high-affinity binding to immobilized VTNC.(A) Sensorgrams for Cyr61 (in nM: a, 40; b, 20; c, 5; d, 2.5) binding to immobilized monomeric VTNC. (B) Sensorgrams show Cyr61 (in nM: a, 50; b, 25, c, 12.5; d, 6.25) binding to multimeric VTNC. Data were fitted using global two-state binding model. RU, resonance units. (C) and (D) solid-phase-binding assay for Cyr61 (0–1 µM) interaction with immobilized monomeric or multimeric VTNC, respectively. Binding was estimated with anti-Cyr61 monoclonal antibody followed by alkaline-phosphatase labeled anti-mouse secondary antibody and appropriate substrate as described in Materials and Methods. (E) and (F) Semi log-transformation of the data depicted in (C) and (D), respectively. The (apparent) KD values for Cyr61/VTNC interactions were calculated by nonlinear regression analysis of the binding data according to the Langmuir isotherm equation. All treatments were performed in quadruplicate or quintuplicate (n = 3).
