IL-12 p70/IL12A Protein Overview: Sequence, Structure, Function and Protein Interaction

IL-12 p70/IL12A Protein Overview

IL-12 p70/IL12A reagents

IL12A, or p35, is a subunit in 2 distinct heterodimeric cytokines: interleukin-12 (IL12) and IL35. IL12 is composed of 40-kD (p40, or IL12B; 161561) and 35-kD (p35) subunits and functions to activate and link the innate and acquired immune responses (Wolf et al., 1994). IL35, an inhibitory cytokine involved in regulatory T-cell function, is composed of Epstein-Barr virus (EBV)-induced gene-3 (EBI3; 605816) and the ubiquitously expressed p35 subunit of IL12 (Niedbala et al., 2007; Collison et al., 2007).
