Weight	1 lbs
Dimensions	9 × 5 × 2 in
accession	P78552
express system	HEK293
product tag	C-hFc
purity	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
background	Two type 1 membrane proteins belonging to the hemopoietin receptor family have been cloned and shown to bind IL-13 with differing affinities. The lower affinity IL-13 binding protein, previously designated IL-13 R alpha, IL-13 R alpha ' or NR4, is now referred to as IL-13 R alpha 1. The high-affinity IL-13 binding protein, previously also designated IL-13 R or IL-13 R alpha ', is now referred to as IL-13 R alpha 2.
molecular weight	The protein has a predicted MW of 63.4 kDa. Due to glycosylation, the protein migrates to 78-90 kDa based on Tris-Bis PAGE result.
available size	100 µg, 500 µg
endotoxin	Less than 1EU per μg by the LAL method.

Protein names Interleukin-13 receptor subunit alpha-1 (IL-13 receptor subunit alpha-1) (IL-13R subunit alpha-1) (IL-13R-alpha-1) (IL-13RA1) (Cancer/testis antigen 19) (CT19) (CD antigen CD213a1)
Gene names IL13RA1,IL13RA1 IL13R IL13RA
Protein family Type I cytokine receptor family, Type 5 subfamily
Mass 9606Da
Function Binds with low affinity to interleukin-13 (IL13). Together with IL4RA can form a functional receptor for IL13. Also serves as an alternate accessory protein to the common cytokine receptor gamma chain for interleukin-4 (IL4) signaling, but cannot replace the function of IL2RG in allowing enhanced interleukin-2 (IL2) binding activity.
Subellular location Membrane; Single-pass type I membrane protein.
Tissues Ubiquitous. Highest levels in heart, liver, skeletal muscle and ovary; lowest levels in brain, lung and kidney. Also found in B-cells, T-cells and endothelial cells.
Structure Interleukin-13 receptor is a complex of IL4R, IL13RA1, and possibly other components. Interacts with TRAF3IP1. Interacts with IL4 (PubMed:18243101).
