Also known as: Ym2; Chi3l4
Summary: Predicted to enable chitin binding activity; chitinase activity; and kinase binding activity. Predicted to be involved in chitin catabolic process; positive regulation of chemokine production; and production of molecular mediator involved in inflammatory response. Located in cytoplasm. Is expressed in several structures, including alimentary system; genitourinary system; liver; lung; and smooth muscle tissue. Human ortholog(s) of this gene implicated in asthma. Orthologous to human CHIA (chitinase acidic). [provided by Alliance of Genome Resources, Dec 2024]

Chitinase-Like Protein Ym2 (Chil4) Regulates Regeneration of the Olfactory Epithelium via Interaction with Inflammation.
Title: Chitinase-Like Protein Ym2 (Chil4) Regulates Regeneration of the Olfactory Epithelium via Interaction with Inflammation.
Production of Ym1/2 in response to interleukin-13 promotes T helper type (Th)2 cell cytokine production and allergic airway inflammation by inhibiting the production of 12(S)-hydroxyeicosatetraenoic acid (HETE) by 12/15(S)-lipoxygenase (LOX).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
