Protein Complexes Involved
Chromatin structure oriented factors:
(HMTs (Histone MethylTransferases)):
COMPASS§† - (COMplex of Proteins ASsociated with Set1) - Methylates lysine 4 of histone H3.
Ser2 - Methylates lysine 36 of histone H3.
(interesting irrelevant example: Dot1*‡ - Methylates lysine 79 of histone H3.)
(Other): Bre1 - Ubiquinates (adds ubiquitin to) lysine 123 of histone H2B. Associated with pre-initiation and allowing RNA Pol II binding.

Famous quotes containing the words protein and/or involved:
“Firm-style bean curd insoles cushion feet, absorb perspiration and provide more protein than meat or fish innersoles of twice the weight. Tofu compresses with use, becoming more pungent and flavorful. May be removed when not in use to dry or marinate. Innersoles are ready to eat after 1,200 miles of wear. Each pair provides adult protein requirement for 2 meals. Insoles are sized large to allow for snacks. Recipe booklet included.”
—Alfred Gingold, U.S. humorist. Items From Our Catalogue, “Tofu Innersoles,” Avon Books (1982)
“In the United States, it is now possible for a person eighteen years of age, female as well as male, to graduate from high school, college, or university without ever having cared for, or even held, a baby; without ever having comforted or assisted another human being who really needed help. . . . No society can long sustain itself unless its members have learned the sensitivities, motivations, and skills involved in assisting and caring for other human beings.”
—Urie Bronfenbrenner (b. 1917)
