Target Details

Target: IL13 Receptor alpha 1 (IL13RA1) (Interleukin 13 Receptor, alpha 1 (IL13RA1))

Alternative Name: IL-13Ra1

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: 63.4 kDa. Due to glycosylation, the protein migrates to 78-90 kDa based on Tris-Bis PAGE result.

UniProt: P78552
