Members of the MARCH family play important roles in regulating immune system and protein transport in cells, especially in antiviral immune responses. Studies have shown that MARCH affects viral replication by regulating the activity of signaling molecules, impacting host immune defense systems.
Membrane-associated RING (really interesting new gene)-cysteine-histidine (CH) (MARCH) ubiquitin ligases belong to a RING finger domain E3 ligases family. So far, eleven members have been found in the MARCH family, which are MARCH 1 to 11. The members of the MARCH family are widely distributed and involve in a variety of cellular functions, including regulation of the immune system, transmembrane transport of proteins, protein stability, endoplasmic reticulum-related degradation, and endosome protein transport. Several seminal studies over the past decade have delineated that MARCH affects viral replication through various mechanisms by regulating the activity of signaling molecules and their expression in the antiviral innate immune responses. Here, we summarize the complex roles of MARCH ligases in the antiviral innate immune signaling pathway and its impact on viral replication in host immune defense systems. A better understanding of this interplay's molecular mechanisms is important concerning the development of new therapeutics targeting viral infections. (C) 2021 Elsevier B.V. All rights reserved.
