IL-1RAcP/IL-1 R3 Protein, Mouse (347a.a, HEK293, His)

IL-1RAcP is a co-receptor for IL1RL2, IL1R1 and IL1RL1 in the IL-36, IL-1 and IL-33 signaling system, respectively. IL-1RAcP is an essential component of the IL-1 receptor and plays an essential role in the inflammatory process^[1][2]. IL-1RAcP/IL-1 R3 Protein, Mouse (347a.a, HEK293, His) is a recombinant mouse IL-1RAcP protein with a His tag at the C-terminus and is expressed in HEK293 cells. It consists of 347 amino acids (S21-T367).

Interleukin-1 receptor accessory protein (IL-1RAcP), also known as IL-1 R3, belongs to the immunoglobulin (Ig) superfamily. IL-1RAcP can be detected in liver, skin, placenta, thymus and lung. IL-1RAcP expression correlates with IL-1 responsiveness in a subclone of the murine lymphoma cell line, EL4.
The mouse IL-1RAcP protein shares 89.12% a.a sequence identity with human, 95.09% identity with rat.
IL-1RAcP contains three Ig-like domains and a cytoplasmic domain named Toll/IL-1 receptor (TIR) (position: 403-546 a.a), which has been implicated in signal transduction. IL-1RAcP also contains a single transmembrane region. IL-1RAcP is a co-receptor for IL1RL2, IL1R1 and IL1RL1 in the IL-36, IL-1 and IL-33 signaling system, respectively. IL-1RAcP is an indispensible molecule in the IL-1 receptor signal transduction complex, links events at the plasma membrane level to downstream signaling pathways, mediates interleukin-1-dependent transcription factor activation and gene expression.
IL-1RAcP plays an essential role in the inflammatory process and can be used for the research of obesity, diabetics, endometriosis, atherosclerosis, and so on^[1][2][3].
