CCN1

Also known as GIG1, IGFBP10, cysteine rich angiogenic inducer 61, cellular communication network factor 1, CYR61

CCN family member 1 (CCN1) or Cysteine-rich angiogenic inducer 61 (CYR61), is a matricellular protein that in humans is encoded by the CYR61 gene.

The secreted protein encoded by this gene is growth factor-inducible and promotes the adhesion of endothelial cells. The encoded protein interacts with several integrins and with heparan sulfate proteoglycan. This protein also plays a role in cell proliferation, differentiation, angiogenesis, apoptosis, and extracellular matrix formation. [provided by RefSeq, Sep 2011].

CCN family member 1 (CCN1) or Cysteine-rich angiogenic inducer 61 (CYR61), is a matricellular protein that in humans is encoded by the CYR61 gene.

CCN1 is a secreted, extracellular matrix (ECM)-associated signaling protein of the CCN family (CCN intercellular signaling protein). CCN1 is capable of regulating a broad range of cellular activities, including cell adhesion, migration, proliferation, differentiation, apoptosis, and senescence through interaction with cell surface integrin receptors and heparan sulfate proteoglycans. During embryonic development, CCN1 is critical for cardiac septal morphogenesis, blood vessel formation in placenta, and vascular integrity. In adulthood CCN1 plays important roles in inflammation and tissue repair, and is associated with diseases related to chronic inflammation, including rheumatoid arthritis, atherosclerosis, diabetes-related nephropathy and retinopathy, and many different forms of cancers.
