CD121b / IL1R2

interleukin 1 receptor, type II

Non-signaling receptor for IL1A, IL1B and IL1RN. Reduces IL1B activities. Serves as a decoy receptor by competetive binding to IL1B and preventing its binding to IL1R1. Also modulates cellular response through non-signaling association with IL1RAP after binding to IL1B. IL1R2 (membrane and secreted forms) preferentially binds IL1B and poorly IL1A and IL1RN. The secreted IL1R2 recruits secreted IL1RAP with high affinity; this complex formation may be the dominant mechanism for neutralization of IL1B by secreted/soluble receptors.

Gene Name: interleukin 1 receptor, type II
Family/Subfamily: Interleukin
Synonyms: IL1R2, CD121b, CD121b antigen, CDw121b, IL-1RT-2, IL1R2c, Interleukin-1 receptor beta, Interleukin-1 receptor type II, IL-1R-beta, Antigen CDw121b, IL-1 type II receptor, IL-1R-2, IL-1RT2, IL1RB, Interleukin-1 receptor type 2
Target Sequences: NM_004633 NP_004624.1 P27930

CD121b / IL1R2 Antibody - Anti-IL-1RII Antibody - Western Blot. Western blot of anti-IL-1RII antibody. This blot shows detection of an IL-1RII-GST fusion protein (~500 ng, lane 1, green, 800 nm channel). Minimal reactivity is observed against GST (data not shown). Protein was resolved on a 4-20% Tris-Glycine gel by SDS-PAGE and transferred onto nitrocellulose. After blocking, the membrane was probed with the primary antibody diluted to 1:1000. Incubation was for 2 hrs at room temperature followed by washes and reaction with a 1:10000 dilution of IRDye 800 conjugated Gt-a-Rabbit IgG (H&L) MX10 ( for 45 min at room temperature. Molecular weight markers are shown for size comparison (lane M, red, 700 nm channel). IRDye 800 fluorescence image was captured using the Odyssey Infrared Imaging System developed by LI-COR. IRDye is a trademark of LI-COR, Inc. Other detection systems will yield similar results.
