Flavonoids may protect against damage by ultraviolet Light

Isoflavonoids have antimicrobial activity

Isoflavonoids are found mostly in legumes such as the rotenoids, have strong insecticidal actions; others have anti-estrogenic effects. 

For example, sheep grazing on clover rich in isoflavonoids often suffer from infertility

WASp activation requires two signals (This type of two-signal input, called coincidence detection):

1. regulatory phospholipid PIP2

2. small GTP-binding protein Cdc42
