CC -!- FUNCTION: Cytokine that binds to and signals through the IL1RL1/ST2
CC receptor which in turn activates NF-kappa-B and MAPK signaling pathways
CC in target cells. Involved in the maturation of Th2 cells inducing the
CC secretion of T-helper type 2-associated cytokines. Also involved in
CC activation of mast cells, basophils, eosinophils and natural killer
CC cells. Acts as a chemoattractant for Th2 cells, and may function as an
CC 'alarmin', that amplifies immune responses during tissue injury (By
CC similarity). {ECO:0000250}.
CC -!- FUNCTION: In quiescent endothelia the uncleaved form is constitutively
CC and abundantly expressed, and acts as a chromatin-associated nuclear
CC factor with transcriptional repressor properties, it may sequester
CC nuclear NF-kappaB/RELA, lowering expression of its targets. This form
CC is rapidely lost upon angiogenic or pro-inflammatory activation (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Forms a 1:1:1 heterotrimeric complex with its primary high-
CC affinity receptor IL1RL1 and the coreceptor IL1RAP. Interacts with
CC cargo receptor TMED10; the interaction mediates the translocation from
CC the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate
CC compartment) and thereby secretion. {ECO:0000250|UniProtKB:O95760}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:O95760}.
CC Chromosome {ECO:0000250|UniProtKB:O95760}. Cytoplasm
CC {ECO:0000250|UniProtKB:O95760}. Cytoplasmic vesicle, secretory vesicle
CC {ECO:0000250|UniProtKB:O95760}. Secreted
CC {ECO:0000250|UniProtKB:O95760}. Note=Associates with heterochromatin
CC and mitotic chromosomes. The secretion is dependent on protein
CC unfolding and facilitated by the cargo receptor TMED10; it results in
CC protein translocation from the cytoplasm into the ERGIC (endoplasmic
CC reticulum-Golgi intermediate compartment) followed by vesicle entry and
CC secretion. {ECO:0000250|UniProtKB:O95760}.
CC -!- DOMAIN: The homeodomain-like HTH domain mediates nuclear localization
CC and heterochromatin association. {ECO:0000250}.
CC -!- PTM: The full-length protein can be released from cells and is able to
CC signal via the IL1RL1/ST2 receptor. However, proteolytic processing by
CC CSTG/cathepsin G and ELANE/neutrophil elastase produces C-terminal
CC peptides that are more active than the unprocessed full-length protein.
CC May also be proteolytically processed by calpains. Proteolytic cleavage
CC mediated by apoptotic caspases including CASP3 and CASP7 results in
CC IL33 inactivation. In vitro proteolytic cleavage by CASP1 was reported
CC but could not be confirmed in vivo suggesting that IL33 is probably not
CC a direct substrate for that caspase (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the IL-1 family. Highly divergent.
CC {ECO:0000305}.
