Product details
ab187480 is a heterodimer of IL-12A (amino acids 23 - 219; UniProt P29459) and IL-12B (amino acids 23 - 328; UniProt P29460) linked through a disulfide-bond between cysteines. The molecular weight of IL-12A (p35) is 23.3 kDa (203aa). The molecular weight of IL-12B (p40) is 34.6 kDa (306aa). The heterodimeric IL-12 has a predicted molecular weight of 57.9kDa
Molecular weight on SDS-PAGE will appear higher.

Function
Heterodimerizes with IL12B to form the IL-12 cytokine or with EBI3/IL27B to form the IL-35 cytokine (PubMed : 8605935, PubMed : 8943050). IL-12 is primarily produced by professional antigen-presenting cells (APCs) such as B-cells and dendritic cells (DCs) as well as macrophages and granulocytes and regulates T-cell and natural killer-cell responses, induces the production of interferon-gamma (IFN-gamma), favors the differentiation of T-helper 1 (Th1) cells and is an important link between innate resistance and adaptive immunity (PubMed : 1673147, PubMed : 1674604, PubMed : 8605935). Mechanistically, exerts its biological effects through a receptor composed of IL12R1 and IL12R2 subunits (PubMed : 8943050). Binding to the receptor results in the rapid tyrosine phosphorylation of a number of cellular substrates including the JAK family kinases TYK2 and JAK2 (PubMed : 7528775). In turn, recruited STAT4 gets phosphorylated and translocates to the nucleus where it regulates cytokine/growth factor responsive genes (PubMed : 7638186). As part of IL-35, plays essential roles in maintaining the immune homeostasis of the liver microenvironment and functions also as an immune-suppressive cytokine (By similarity). Mediates biological events through unconventional receptors composed of IL12RB2 and gp130/IL6ST heterodimers or homodimers (PubMed : 22306691). Signaling requires the transcription factors STAT1 and STAT4, which form a unique heterodimer that binds to distinct DNA sites (PubMed : 22306691).
