Trends Cell Biol. 2021 Aug;31(8):686-701. doi: 10.1016/j.tcb.2021.04.002. Epub 2021 May 4.

Abstract

The HORMA domain protein REV7, also known as MAD2L2, interacts with a variety of proteins and thereby contributes to the establishment of different complexes. With doing so, REV7 impacts a diverse range of cellular processes and gained increasing interest as more of its activities became uncovered. REV7 has important roles in translesion synthesis and mitotic progression, and acts as a central component in the recently discovered shieldin complex that operates in DNA double-strand break repair. Here we discuss the roles of REV7 in its various complexes, focusing on its activity in genome integrity maintenance. Moreover, we will describe current insights on REV7 structural features that allow it to be such a versatile protein.

Keywords: HORMA; REV7; genome maintenance; shieldin; translesion synthesis.
