MGI Phenotype Strain: 4355925
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a subunit of the receptor for IL23A/IL23. This protein pairs with the receptor molecule IL12RB1/IL12Rbeta1, and both are required for IL23A signaling. This protein associates constitutively with Janus kinase 2 (JAK2), and also binds to transcription activator STAT3 in a ligand-dependent manner. [provided by RefSeq, Jul 2008]
PHENOTYPE: Th17 T cells from homozygous null mice have less secretion of IL-9 upon secondary stimulation. [provided by MGI curators]

Protein Function and Prediction

IL23R is a member of the hemopoietin receptor family that pairs with IL-12Rβ1 to respond to IL-23 (1).  IL23R mediates the inflammatory response via the production of IL-17 by Th17 lymphocytes (2). Functional IL23R pathway polymorphisms are proposed to function in modulating neonatal development of intestinal tolerance and bacterial colonization (2).

Expression/Localization

Il23R is expressed in Th1, Th0, and NK cell lines; slight expression is observed in monocytes, dendritic cells, or B-cell lines (1).  Another study determined that IL23R is expressed on the cell membrane of memory T cells and other immune cells, such as natural killer cells, monocytes, and dendritic cells (2).

Background

Mutations in IL23R are linked to protection against inflammatory bowel disease 17 [OMIM: #612261; (3;4)] and protection against psoriasis [OMIM: %605606].

 

Il23rtm1.1Kuch/tm1.1Kuch; MGI:4355925

involves: C57BL/6

Th17 T cells from homozygous null mice have less secretion of IL-9 upon secondary stimulation (5).

 

Il23rtm1Dnax/tm1Dnax; MGI:3665279

C57BL/6-Il23rtm1Dnax

Injected B16F10 melanoma and LL2 lung carcinoma cells are inhibited from growing in homozygotes (6). Homozygotes also do not exhibit epidermal hyperplasia in response to intradermal IL-23 treatment (7).
