產(chǎn)品描述：

The recombinant CD74 protein gene sequence Gln73-Met232 fused with an N-terminal 10xHis-tag was inserted into the prokaryotic expression vector to obtain the recombinant plasmid, which was transferred into mammalian cells for further expression. The final product is the recombinant human CD74 protein. Its purity reaches up to 95%. Its endotoxin and activity have been measured.

CD74 is the receptor for the cytokine MIF. CD74-MIF interaction activates CD74/CD44 complex further inducing the activation of ERK, PI3K-Akt, NF-κB, and AMPK pathways involved in cell proliferation and survival. Additionally, CD74-MIF signaling plays a vital role in protecting against injury and promoting healing in different body parts. CD74 also participates in the modulation of T cell and B cell development, dendritic cell (DC) motility, macrophage inflammation, and thymic selection. Many studies have shown that CD74 is complicated in the pathogenesis of many inflammatory diseases, such as Alzheimer's disease, systemic lupus erythematosus, and type I diabetes. CD74 expression has been proposed as a prognostic factor in numerous malignancies, with higher relative expression acting as a sign of tumor progression.

靶點(diǎn)詳情

功能：

Plays a critical role in MHC class II antigen processing by stabilizing peptide-free class II alpha/beta heterodimers in a complex soon after their synthesis and directing transport of the complex from the endoplasmic reticulum to the endosomal/lysosomal system where the antigen processing and binding of antigenic peptides to MHC class II takes place. Serves as cell surface receptor for the cytokine MIF.; Binds to the peptide-binding site of MHC class II alpha/beta heterodimers forming an alpha-beta-CLIP complex, thereby preventing the loading of antigenic peptides to the MHC class II complex until its release by HLA-DM in the endosome.; Stabilizes the conformation of mature CTSL by binding to its active site and serving as a chaperone to help maintain a pool of mature enzyme in endocytic compartments and extracellular space of antigen-presenting cells (APCs). Has antiviral activity by stymieing the endosomal entry of Ebola virus and coronaviruses, including SARS-CoV-2. Disrupts cathepsin-mediated Ebola virus glycoprotein processing, which prevents viral fusion and entry. This antiviral activity is specific to p41 isoform.
