name: histone H2B type 1-K, initiator methionine removed ubiquitinated 1 (human)
def: "A histone H2B type 1-K (human) that has had the initiator methionine removed and that has been ubiquitinated on the lysine at the position equivalent to Lys-121 of the amino acid sequence represented by UniProtKB:O60814. UniProtKB:O60814, 2-126, Lys-121, MOD:01148." [PRO:DAN, PRO:JPB, PRO:JR, PMID:16307923, PMID:16713563, PMID:18400894, PMID:18832071, PMID:18923072, PMID:19575011, HIstome_var_Hs:Histone_H2B_type_1-K]
