IL-31 Protein, Human (HEK293, His)

IL-31 is a multifunctional cytokine that activates STAT3 through IL-31 heterodimeric receptors (IL31RA and OSMR) and may activate STAT1 and STAT5. IL-31 is known for its involvement in skin immunity, where it regulates immune responses. IL-31 Protein, Human (HEK293, His) is the recombinant human-derived IL-31 protein, expressed by HEK293 , with C-His labeled tag.

IL-31, a cytokine with diverse functions, acts by activating STAT3, and potentially STAT1 and STAT5, utilizing the IL-31 heterodimeric receptor formed by IL31RA and OSMR. This activation mechanism has been implicated in skin immunity, highlighting its role in modulating immune responses. Additionally, IL-31 exhibits the capacity to enhance myeloid progenitor cell survival in vitro, emphasizing its involvement in cellular processes beyond immune regulation. Furthermore, IL-31 induces the expression of key genes, such as RETNLA and serum amyloid A protein, in macrophages, suggesting a broader impact on inflammatory and immune-related pathways.
