Target Details

Target: IL-17A/F (Interleukin-17 A/F Heterodimer (IL-17A/F))

Alternative Name: IL-17A&F (IL-17A/F Products)

Background: Interleukin-17A (IL-17A), also known as CTLA-8, is a 15-20 kDa glycosylated cytokine that plays an important role in anti-microbial and chronic inflammation. The six IL-17 cytokines (IL-17A-F) are encoded by separate genes but adopt a conserved cystine knot fold.IL-17A is a ligand for IL17RA and IL17RC. The heterodimer formed by IL17A and IL17F is a ligand for the heterodimeric complex formed by IL17RA and IL17RC. Involved in inducing stromal cells to produce proinflammatory and hematopoietic cytokines.

Molecular Weight: 15.1 kDa (IL-17A) & 15.7 kDa (IL-17F). Due to glycosylation, the protein migrates to 16 kDa & 27 kDa based on Tris-Bis PAGE result.
