A receptor for green tea polyphenol EGCG.
The major polyphenol in green tea, (-)-epigallocatechin-3-gallate (EGCG), has been shown to prevent carcinogenesis. We have identified a receptor that mediates the anticancer activity of EGCG. Expression of the metastasis-associated 67-kDa laminin receptor confers EGCG responsiveness to cancer cells at physiologically relevant concentrations. Experiments using surface plasmon resonance demonstrate binding of EGCG to the 67-kDa laminin receptor with a nanomolar K (d) value.
