ISG15 Ubiquitin-Like Modifier encoded by ISG15 is a ubiquitin-like protein that is conjugated to intracellular target proteins upon activation by interferon-alpha and interferon-beta. Several functions have been ascribed to the encoded protein, including chemotactic activity towards neutrophils, direction of ligated target proteins to intermediate filaments, cell-to-cell signaling, and antiviral activity during viral infections. While conjugates of this protein have been found to be noncovalently attached to intermediate filaments, ISG15 Ubiquitin-Like Modifier is sometimes secreted. ISG15 (ISG15 Ubiquitin-Like Modifier) is a Protein Coding gene. Diseases associated with ISG15 include Immunodeficiency 38 and Influenza. Among its related pathways are Type II interferon signaling (IFNG) and Translesion synthesis by Y family DNA polymerases bypasses lesions on DNA template.
