ISG15 E1/UBE1L
-
简介
The ISG15 E1/UBE1L protein initiates ubiquitination by adenylating the C-terminal glycine of ubiquitin with ATP to form a thioester bond with its cysteine residue. This produces ubiquitin-E1 thioester and free AMP. ISG15 E1/UBE1L Protein, Human (sf9, His, Strep) is the recombinant human-derived ISG15 E1/UBE1L protein, expressed by Sf9 insect cells , with N-8*His, N-Strep labeled tag.

稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Protein Description
ISG15 (Interferon-stimulated gene 15) is a ubiquitin-like protein that plays a crucial role in the immune response, particularly in the regulation of antiviral and inflammatory processes. The E1 enzyme UBE1L (ubiquitin-activating enzyme 1-like) is responsible for the initial step in the ISG15 conjugation pathway, activating ISG15 for subsequent transfer to target proteins, a process known as ISGylation. This post-translational modification has been implicated in various biological functions, including protein stability, localization, and activity modulation, thereby influencing cellular responses to stress and pathogen invasion. Research has shown that ISGylation can enhance the antiviral capabilities of host cells and modulate the immune system's response, making it a key area of interest in the study of host-pathogen interactions and immune regulation. The exploration of ISG15 and UBE1L, particularly through recombinant protein studies, provides valuable insights into their functional mechanisms and their potential as therapeutic targets in diseases characterized by dysregulated immune responses, such as cancer and autoimmune disorders. Understanding the biochemistry and biological roles of both ISG15 and UBE1L can pave the way for novel strategies in the development of antiviral therapies and immunomodulatory treatments.
