CC -!- FUNCTION: Homodimeric cytokine expressed predominantly by T-lymphocytes
CC and NK cells that plays an important role in the survival,
CC differentiation, and chemotaxis of eosinophils. Acts also on activated
CC and resting B-cells to induce immunoglobulin production, growth, and
CC differentiation (By similarity). Mechanistically, exerts its biological
CC effects through a receptor composed of IL5RA subunit and the cytokine
CC receptor common subunit beta/CSF2RB. Binding to the receptor leads to
CC activation of various kinases including LYN, SYK and JAK2 and thereby
CC propagates signals through the RAS-MAPK and JAK-STAT5 pathways
CC respectively (By similarity). {ECO:0000250|UniProtKB:P04401,
CC ECO:0000250|UniProtKB:P05113}.
CC -!- SUBUNIT: Homodimer; disulfide-linked. Interacts with IL5RA. Interacts
CC with CSF2RB. {ECO:0000250|UniProtKB:P04401,
CC ECO:0000250|UniProtKB:P05113}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P04401}.
CC -!- SIMILARITY: Belongs to the IL-5 family. {ECO:0000305}.
