CC   -!- FUNCTION: Participates in at least several B-cell activation processes
CC       as well as of other cell types. It is a costimulator of DNA-synthesis.
CC       It induces the expression of class II MHC molecules on resting B-cells.
CC       It enhances both secretion and cell surface expression of IgE and IgG1.
CC       It also regulates the expression of the low affinity Fc receptor for
CC       IgE (CD23) on both lymphocytes and monocytes. Positively regulates
CC       IL31RA expression in macrophages. Stimulates autophagy in dendritic
CC       cells by interfering with mTORC1 signaling and through the induction of
CC       RUFY4. {ECO:0000250|UniProtKB:P07750}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the IL-4/IL-13 family. {ECO:0000305}.
