Histone fulfills a number of functions:

DNA binding – SUMO binding – sequence-specific DNA binding – protein binding

Histone is relevant to the following processes:

cellular response to DNA damage stimulus – chromatin assembly or disassembly – nucleosome assembly – defense response – embryo development ending in birth or egg hatching – locomotion – pharynx development – growth – nematode larval development – body morphogenesis – positive regulation of growth rate – hermaphrodite genitalia development – positive regulation of locomotion – reproduction – DNA repair – regulation of transcription, DNA-dependent – embryonic development ending in birth or egg hatching – determination of adult lifespan – response to DNA damage stimulus – germ cell development – germline cell cycle switching, mitotic to meiotic cell cycle – oviposition

Locations for Histone:

chromosome – lipid particle – nucleosome – nucleus – polytene chromosome – intracellular – NuA4 histone acetyltransferase complex – chromatin – cytoplasm
