• Sequence Length: 270

• Applicable Applications for IL33 active protein: User optimized
• Protein Type: Recombinant
• Biological Significance: Human IL31 is a T-cell derived cytokine that shares several structural and functional characteristics with IL6, Oncostatin M, LIF, and Cardiotrophin-1. It signals through a receptor complex comprised of GPL (GP130-like, IL31RA) and OSMR (Oncostatin M receptor). GPL/OSMR signaling is a strong activator of STAT3 and STAT5, and can also activate STAT1, Jak1, and Jak2 signaling pathways. IL31 regulated immune responses have been implicated in skin physiology and inflammatory skin diseases.
• Bioactivity: The ED50 was determined by the dose-dependent stimulation of the proliferation of Mouse D10S cells is approximately 0.05 ng/ml, corresponding to a specific activity of approximately 2 x 10^7units/mg.
• Endotoxin Levels: Endotoxin level is less than 0.1 ng per ug (1 EU/ug).
• Expression System: E Coli
• Preparation and Storage: Store at 4 degree C until reconstitution. Following reconstitution aliquot and freeze at -20 degree C for long term storage. Avoid repeated freeze/thaw cycles.

NCBI Description

IL33 (MIM 608678) is a member of the IL1 (see MIM 147760) family that potently drives production of T helper-2 (Th2)-associated cytokines (e.g., IL4; MIM 147780). IL33 is a ligand for IL33R (IL1RL1; MIM 601203), an IL1 family receptor that is selectively expressed on Th2 cells and mast cells (summary by Yagami et al., 2010 [PubMed 20926795]).[supplied by OMIM, Jan 2011]

Uniprot Description

IL33: Cytokine that binds to and signals through IL1RL1/ST2 and its stimulation recruits MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. Induces T-helper type 2-associated cytokines. Belongs to the IL-1 family. Highly divergent. 2 isoforms of the human protein are produced by alternative splicing.
