Détail du antigène

Antigène: Interleukin 17a (IL17A) (Interleukin 17A (IL17A))

Autre désignation: IL-17A

Sujet: IL-17A was initially identified from a subtracted cDNA library between closely related murine lymphoid cells and called CTLA-8. IL-17A shares 58 % homology with an open reading frame of the T-lymphotropic Herpes virus Samirii virus (viral IL-17). IL-17A belongs to a family of cytokines, which has five members, designated IL-17A-F. IL-17 is expressed by a unique lineage of CD4 T cells, Th17 cells. This lineage selectively produces proinflammatory cytokines including IL-17, IL-17F, IL-21, and IL-22. In the mouse, the differentiation of this new lineage is initiated by TGFbeta-1 and IL-6 or IL-21, which activates Stat3 and induces the expression of the transcription factor retinoic acid-related orphan receptors (RORγt and RORα). IL-23, which also activates Stat3, serves to maintain Th17 cells lineage.

Poids moléculaire: The 133 amino acid recombinant protein has a predicted molecular mass of 14,978 Da. This protein exists as a disulfide-linked homodimer. The DTT-reduced protein migrates at approximately 15kDa by SDS-PAGE. The non-reduced protein migrates as a homodimer,
