General Information of Binding Target of SBP (BTS) (ID: ST00133)
BTS Name
Interleukin-4
Synonyms
IL-4; B-cell stimulatory factor 1; BSF-1; Binetrakin; Lymphocyte stimulatory factor 1; Pitrakinra
BTS Type
Protein
Family
IL-4/IL-13 family
Gene Name
IL4
Organism
Homo sapiens (Human)
Function
Participates in at least several B-cell activation processes as well as of other cell types It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. Positively regulates IL31RA expression in macrophages (By similarity). Stimulates autophagy in dendritic cells by interfering with mTORC1 signaling and through the induction of RUFY4 (By similarity).
