This cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. This gene, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.

A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and\/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors.,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\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSpecies:\u003c\/b\u003e Human;Mouse\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRange:\u003c\/b\u003e WB;Flow Cyt;ELISA\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eProtein:\u003c\/b\u003e Interleukin-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDA:\u003c\/b\u003e 18kD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Upingbio","offers":[{"title":"100UL","offer_id":50691393093912,"sku":"YP-Ab-15937-100UL","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/images_ace10a7d-403d-4add-abcd-979bd4f0e649.png?v=1758628555","url":"https:\/\/danabiosci.com\/products\/yp-ab-15937-100ul","provider":"Dana Bioscience","version":"1.0","type":"link"}
