产品信息

背景说明： Human Interleukin 31 (IL-31) is a cytokine containing a four-helix bundle structure.It shares several structural and functional characteristics with IL-6，Oncostatin M，LIF，and Cardiotrophin-1.Human IL-31 cDNA encodes a 164 amino acid precursor that contains a 23 amino acid signal peptide and a 141 amino acid mature protein.Human and mouse IL-31 share 24% sequence identity in the mature region.IL-31 is mainly associated with activated T cells and is preferentially expressed by type 2 helper T cells (Th2).IL-31 signals via a heterodimeric receptor complex composed of a gp130 related molecule termed IL-31RA (also GPL and GLMR) and an Oncostatin M receptor (OSM Rβ).The IL-31 receptor is constitutively expressed by keratinocytes and upregulated by IFNγ on monocytes.GPL/OSMR signaling is a strong activator of STAT3 and STAT5，and can also activate STAT1，Jak1，and Jak2 signaling pathways.IL-31 regulated immune responses have been implicated in skin physiology and inflammatory skin diseases.Studies have shown that IL31 induces severe pruritis (itching) and dermatitis in transgenic mice.
