Immunocytochemistry/Immunofluorescence: Cyr61/CCN1 Antibody [NB100-357] - CYR61 antibody was tested in MCF-7 cells with DyLight 488 (green). Nuclei and alpha-tubulin were counterstained with DAPI (blue) and Dylight 550 (red).

Simple Western: Cyr61/CCN1 Antibody [NB100-357] - Simple Western lane view shows a specific band for Cyr61 in 0.2 mg/ml of MCF-7 lysate. This experiment was performed under reducing conditions using the 12-230 kDa separation system. *Non-specific interaction with the 230 kDa standard may be seen with this antibody.

Background

CYR61 (cysteine-rich angiogenic inducer 61), a heparin-binding growth factor, belongs to CCN family whose members are: cysteine-rich 61 (CYR61/CCN1), connective tIssue growth factor (CTGF/CCN2), nephroblastoma overexpressed (NOV/CCN3), and Wnt-induced secreted proteins-1 (WISP-1/CCN4), -2 (WISP-2/CCN5) and -3 (WISP-3/CCN6). CYR61 localizes intracellularly or associates with extracellular matrix at cell surfaces and its reported nuclear localization is surprising, since the primary structure of CYR61 does not include a classic nuclear localization sequence, however, like NOV, EGF, FGF, PDGF, angiogenin, PTHrP etc which lack afore-mentioned sequence, CYR61's nuclear presence may be correlated with transcriptional regulation, and/or mRNA transport. CYR61 plays a key role in wound healing by up-regulating the expression of several genes involved in angiogenesis, inflammation and matrix remodeling including VEGA-A, VEGA-C, MMP1, MMP3, TIMP1, uPA, PAI-1, integrins alpha-3 and alpha-5. CYR61 down-regulates the expression of alpha-1/alpha-2 subunits of collagen type-1 and promotes cell adhesion/adhesive signaling through integrin alpha-6/beta-1, cell migration through integrin alpha-v/beta-5 and cell proliferation through integrin alpha-v/beta-3. CYR61 has been reported to exert its diverse functions via cross-talk with/activating of Wnt, NFkB, AKT and tyrosine kinase signaling pathways.
