Adenosine Triphosphate 154-157 H3 histone pseudogene 16 Homo sapiens 105-108 24289924-4 2014 Upon DNA damage, cells undergo PARP-1-dependent ATP depletion, which is correlated with reduced TAF1 kinase activity and Thr55 phosphorylation, resulting in p21 activation. Adenosine Triphosphate 48-51 H3 histone pseudogene 16 Homo sapiens 157-160
