The mammalian serine/threonine Akt kinases comprise three closely related isoforms: Akt1, Akt2 and Akt3. Akt activation has been implicated in both normal and disease processes, including in development and metabolism, as well as cancer and cardiovascular disease.
In music, vamping is the repeated use of a phrase through an entire song or the improvisation on top of a repeated phrase through a song. Looping, samples and grooves are all examples of vamping, as is almost all popular music with repeated chord progressions.
