The packaging of chromatin at higher level requires additional set of proteins that collectively are referred as Non - histone chromosomal (NHC) proteins. Non - histone chromosomal proteins are of three types :

(iii) Regulatory NHC protein e.g., HMG (High mobility group proteins that controls gene expression)
