Catalog No. ABIN4949114

Product Details

Target: IL12A & IL27B

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 20-189

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: His tag

Application: Functional Studies (Func)

Sequence: AA 20-189

Characteristics: Human IL-23 alpha & IL-12 beta Heterodimer Protein, produced by co-expression of IL-23 alpha and IL-12 beta, has a calculated MW of 19.5 kDa (IL-23 alpha) and 34.7 kDa (IL-12 beta). Subunit IL-23 alpha is fused with a polyhistidine tag at the N-terminus and subunit IL-12 beta contains no tag. The predicted N-terminus is His (IL23A) & Ile 23 (IL12B). The reducing (R) protein migrates as 20 kDa (IL-23 alpha) and 40-45 kDa (IL-12 beta) respectively due to glycosylation.

Target Details

Target: IL12A & IL27B

Alternative Name: IL23A & IL12B

Background: Interleukin-23 subunit alpha (IL-23 alpha) can associates with IL12B to form the IL-23 interleukin, a heterodimeric cytokine which functions in innate and adaptive immunity. IL-23 may constitute with IL-17 an acute response to infection in peripheral tissues. IL-23 binds to a heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes production of proinflammatory cytokines. IL-23 induces autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis.

Molecular Weight: 19.5 kDa (IL23A) & 34.7 kDa (IL12B)
