Molecule Information: IL-5 Long Name: Interleukin 5 Aliases: BCDF mu; BCGFII; EDF; Eo-CSF; TRF Entrez Gene IDs: 3567 (Human); 16191 (Mouse); 24497 (Rat); 397409 (Porcine); 280825 (Bovine); 403790 (Canine); 493803 (Feline) Background: IL-5 Interleukin 5 (IL-5) is a T cell-derived factor that promotes the proliferation, differentiation and activation of eosinophils. In mice, IL-5 is also a growth and differentiation factor for B cells. Various names previously used to describe IL-5 include: Tcell replacing factor (TRF), B cell growth factor II (BCGFII), B cell differentiation factor µ (BCDF µ), eosinophil differentiation factor (EDF) and eosinophil colony-stimulating factor (Eo-CSF). Biologically active IL-5 is a disulfide-linked homodimer. Rat IL-5 is 94% and 70% identical to mouse and human IL-5, respectively.
