protein serine/threonine kinase activity histone H2A kinase activity histone H2AT120 kinase activity https://github.com/geneontology/go-ontology/issues/28520 https://github.com/geneontology/go-ontology/issues/30578 histone threonine kinase activity (H2A-T120 specific) Note that the residue position corresponds to the canonical human H2A2A histone (UniProtKB:Q6FI13); this residue is conserved across all eukaryotes, but corresponds to T119 in Drosophila and S121 in yeast and Tetrahymena. Residue 1 is the first residue following removal of the initiating Methionine (Met). Note that each histone is encoded by multiple genes, and sequences may vary across different genes within an organism. molecular_function histone H2AS120 kinase activity GO:1990244 2013-12-04T06:38:32Z Catalysis of the reaction: histone H2A-threonine (position 120) + ATP = histone H2A-phosphothreonine (position 120) + ADP. This reaction is the addition of a phosphate group to the threonine residue at position 120 of histone H2A. histone H2A-T120 kinase activity histone kinase activity (H2A-T120 specific) sp
