Protein Information (annotations from UniProt)

Database IDHIV0001421
UniProt IDP05112
Primary gene name(s)IL4
Synonym gene name(s)unknown
Protein nameInterleukin-4
Protein functionParticipates in at least several B-cell activation processes as well as of other cell types, PubMed:3016727. 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. {ECO:0000250|UniProtKB:P07750, ECO:0000269|PubMed:3016727}.
