Biological Roles
Many genes encoding FOX proteins have been identified. For example, the FOXF2 gene encodes forkhead box F2, one of many human homologues of the Drosophila melanogaster transcription factor forkhead. FOXF2 is expressed in lung and placenta.
Some FOX genes are downstream targets of the hedgehog signaling pathway, which plays a role in the development of basal cell carcinomas. Members of the class O regulate metabolism, cellular proliferation, stress tolerance and possibly lifespan. The activity of FoxO is controlled by post-translational modifications, including phosphorylation, acetylation and ubiquitination.

Famous quotes containing the words biological and/or roles:
“No further evidence is needed to show that “mental illness” is not the name of a biological condition whose nature awaits to be elucidated, but is the name of a concept whose purpose is to obscure the obvious.”
—Thomas Szasz (b. 1920)
“It was always the work that was the gyroscope in my life. I don’t know who could have lived with me. As an architect you’re absolutely devoured. A woman’s cast in a lot of roles and a man isn’t. I couldn’t be an architect and be a wife and mother.”
—Eleanore Kendall Pettersen (b. 1916)
