Their  characteristic fold consists of three alpha helices linked by two loops, and they all contain extended tails.
Antibodies against these proteins are found in over 95% of patients with drug-induced lupus. The "spooling" model of  Felsenfeld and "disruptive" model of van Holde have been proposed to explain the positioning of these proteins. Their  characteristic fold consists of three alpha helices linked by two loops, and they all contain extended tails. In yeast, the  Swi/Snf ("switch/sniff") complex remodels their association with another molecule. One of them has a variant designated by a  degree symbol and is also known as the "linker" one. These proteins function as hetero-octamers, and the addition of three methyl  groups to lysine-27 on one of these proteins results in gene silencing, and their acetylation tends to enhance transcription. For 10  points, name these basic proteins that DNA winds around to form chromatin.
