$315.00 – $1,050.00

Summary

Expression: HEK293
Functional: Yes (ELISA)
Amino Acid Range: Ser24-Thr164

SKU: 4097parent Categories: proteins, Recombinant proteins Tag: active proteins

Weight	1 lbs
Dimensions	9 × 5 × 2 in
accession	Q6EBC2
express system	HEK293
product tag	N-His
purity	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
background	Many autoimmune skin diseases, such as bullous pemphigoid (BP), psoriasis and certain types of chronic urticaria, are associated with intensive pruritus. While histamine and neuropeptides have previously been ascribed to play a role in itch that accompanies these diseases, recent evidence suggests that the pruritogenic cytokine interleukin (IL)-31 is a major driver of pruritic responses. IL-31 was originally shown to be produced by activated helper T cells, particularly Th2 cells, mast cells, macrophages and dendritic cells.
molecular weight	The protein has a predicted MW of 16.9 kDa. Due to glycosylation, the protein migrates to 20-25 kDa based on Tris-Bis PAGE result.
available size	100 µg, 500 µg
endotoxin	Less than 1EU per μg by the LAL method.

Function
Activates STAT3 and possibly STAT1 and STAT5 through the IL31 heterodimeric receptor composed of IL31RA and OSMR (PubMed:15184896). May function in skin immunity (PubMed:15184896). Enhances myeloid progenitor cell survival in vitro (By similarity). Induces RETNLA and serum amyloid A protein expression in macrophages (By similarity).
Subellular location
Secreted .
Tissues
Detected at low levels in testis, bone marrow, skeletal muscle, kidney, colon, thymus, small intestine and trachea.
