ISG15 also known as G1P2 is a ubiquitin-like protein with a molecular weight of approximately 17 kDa. This protein gets expressed highly in response to interferon stimulation particularly in white blood cells such as macrophages and monocytes. It consists of two ubiquitin-like domains contributing to its functionality. ISG15 performs its mechanical role by adding itself to target proteins in a process known as ISGylation. This process resembles ubiquitination and serves to modify the functions of targeted proteins.
Biological function summary
ISG15 plays an important role in the immune response to viral infections. It acts as an antiviral agent by inhibiting viral replication. It interacts with and becomes a part of protein complexes modifying cellular proteins involved in immune regulation. ISG15 influences the stability function and localization of these target proteins enhancing antiviral defenses and potentially modulating immune signaling pathways.
Pathways
ISG15 operates within the interferon signaling pathway and the antiviral response pathway. In the interferon signaling pathway ISG15 interacts with proteins like UBE1L and UBE2L6 which act together for effective ISGylation of targets. In the antiviral response pathway ISG15 boosts the effects of proteins like IRF3 and STAT1 enhancing antiviral responses. These interactions allow ISG15 to effectively contribute to halting viral propagation.
ISG15 connects to autoimmune diseases and certain viral infections. In autoimmune conditions like systemic lupus erythematosus abnormal ISG15 activity can contribute to disease pathology. ISG15 also interacts with proteins such as USP18 which regulates the expression of type I interferons to influence the disease processes. Furthermore ISG15 involvement in viral infections such as hepatitis C highlights its value in antiviral defenses. Understanding these interactions can support the development of therapies targeting ISG15 for managing immune-related conditions.
