Mini Sample Human sST2 (Soluble ST2) ELISA Kit

IL-1RL1/ST2 was initially identified in stimulated BALB/3T3 cells and is encoded by the IL-1RL1 gene that produces different isoforms by alternative splicing. In humans, four isoforms have been described: a membrane attached ST2L isoform and a soluble protein (sST2/ IL1RL1-a) that lacks the transmembrane and cytoplasmic domains, which acts as a natural antagonist of IL-33.Gene AliasIL1RL1Gene ID9173Uniport IDQ01638Protein AliasIL1RL1Research AreaImmunology Protein function: Receptor for interleukin-33 (IL-33) which plays crucial roles in innate and adaptive immunity, contributing to tissue homeostasis and responses to environmental stresses together with coreceptor IL1RAP (PubMed:35238669). 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 (Probable) (PubMed:16286016). Upon tissue injury, induces UCP2- dependent mitochondrial rewiring that attenuates the generation of reactive oxygen species and preserves the integrity of Krebs cycle required for persistent production of itaconate and subsequent GATA3- dependent differentiation of inflammation-resolving alternatively activated macrophages.
