Détail du antigène

Antigène: IL-2 (IL2) (Interleukin 2 (IL2))

Autre désignation: IL-2

Sujet: IL-2 was discovered through its function as a T cell growth factor (TCGF), and plays a pivotal role in immune responses against pathogenic infection. Recognition and binding of foreign antigens by T cell receptors stimulate both the secretion of IL-2 and the expression of IL-2Rs on the T cell surface. Subsequently, the IL-2/IL-2R interaction activates the intracellular Ras/Raf/MAPK, JAK/STAT, and PI3K/AKT signal pathways, and ultimately stimulates the growth, differentiation, and survival of the antigen-specific cytotoxic T cells. Human IL-2 acts on murine and human T cells, and its receptors are shared by others cytokines. IL-2Ra is an IL-2-specific receptor, IL-2Rb is shared with IL-15 and the gc is a common receptor shared by many cytokines including IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21.

Poids moléculaire: The 148 amino acid recombinant protein has a predicted molecular mass of 17.2 kDa. The predicted N-terminal amino acid is Phe.
