Interleukin 1 Receptor-Like 1, IL1RL1 (IL1RL1) Antibody – Rabbit Polyclonal

The protein encoded by this gene is a member of the interleukin 1 receptor family. Studies of the similar gene in mouse suggested that this receptor can be induced by proinflammatory stimuli, and may be involved in the function of helper T cells. This gene, interleukin 1 receptor, type I (IL1R1), interleukin 1 receptor, type II (IL1R2) and interleukin 1 receptor-like 2 (IL1RL2) form a cytokine receptor gene cluster in a region mapped to chromosome 2q12. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

Function: Receptor for interleukin-33 (IL-33), its stimulation recruits MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. Possibly involved in helper T-cell function. Ref.11

Subunit structure: Interacts with MYD88, IRAK1, IRAK4, and TRAF6. Ref.11

Subcellular location: Isoform C: Cell membrane Ref.10. Isoform B: Secreted Ref.10. Cell membrane; Single-pass type I membrane protein Ref.10.

Tissue specificity: Highly expressed in kidney, lung, placenta, stomach, skeletal muscle, colon and small intestine. Isoform A is prevalently expressed in the lung, testis, placenta, stomach and colon. Isoform B is more abundant in the brain, kidney and the liver. Isoform C is not detected in brain, heart, liver, kidney and skeletal muscle. Ref.10

Sequence similarities: Belongs to the interleukin-1 receptor family.Contains 3 Ig-like C2-type (immunoglobulin-like) domains.Contains 1 TIR domain.
