Rev7 is a versatile HORMA (Hop1, Rev7, Mad2) family adaptor protein with multiple roles in mitotic regulation and DNA damage response, and an essential accessory subunit of the translesion synthesis (TLS) DNA polymerase Polζ employed in replication of damaged DNA. Within Polζ, the two copies of Rev7 interact with the two Rev7-bonding motifs (RBM1 and RBM2) of the catalytic subunit Rev3 by a mechanism characteristic of HORMA proteins whereby the “safety-belt” loop of Rev7 closes on the top of the ligand. Here we report the nearly complete backbone and Ile, Val, Leu side-chain methyl NMR resonance assignments of the 27 kDa human Rev7/Rev3-RBM1 and Rev7/Rev3-RBM2 complexes (BMRB deposition numbers 51651 and 51652) that will facilitate future NMR studies of Rev7 dynamics and interactions.

人类 Rev7/Rev3-RBM1 和 Rev7/Rev3-RBM2 复合物的骨干和 ILV 侧链甲基 NMR 共振分配

Rev7 是一种多功能 HORMA(Hop1、Rev7、Mad2)家族衔接蛋白,在有丝分裂调节和 DNA 损伤反应中具有多种作用,并且是用于复制受损 DNA 的转位合成 (TLS) DNA 聚合酶 Polζ 的重要辅助亚基。在 Polζ 中,Rev7 的两个拷贝与催化亚基 Rev3 的两个 Rev7 结合基序(RBM1 和 RBM2)通过 HORMA 蛋白的机制特征相互作用,Rev7 的“安全带”环在配体顶部闭合. 在这里,我们报告了 27 kDa 人 Rev7/Rev3-RBM1 和 Rev7/Rev3-RBM2 复合物(BMRB 沉积编号 51651 和 51652)的近乎完整的骨架和 Ile、Val、Leu 侧链甲基 NMR 共振分配,这将促进未来的 NMR Rev7 动力学和相互作用的研究。
