研究背景

功能:

Involved in gastrointestinal immunity. Upon stimulation by muramyl dipeptide (MDP), a fragment of bacterial peptidoglycan, binds the proximal adapter receptor-interacting RIPK2, which recruits ubiquitin ligases as XIAP, BIRC2, BIRC3, INAVA and the LUBAC complex, triggering activation of MAP kinases and activation of NF-kappa-B signaling. This in turn leads to the transcriptional activation of hundreds of genes involved in immune response. Required for MDP-induced NLRP1-dependent CASP1 activation and IL1B release in macrophages. Component of an autophagy-mediated antibacterial pathway together with ATG16L1. Plays also a role in sensing single-stranded RNA (ssRNA) from viruses. Interacts with mitochondrial antiviral signaling/MAVS, leading to activation of interferon regulatory factor-3/IRF3 and expression of type I interferon.

翻译修饰:

Polyubiquitinated following MDP stimulation, leading to proteasome-mediated degradation.

细胞定位:

Cytoplasm. Membrane. Mitochondrion. Basolateral cell membrane.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
组织特异性:

Expressed in intestinal mucosa, mainly in Paneth cells and, at lower extent, in the glandular epithelium.

亚基结构:

Component of a signaling complex consisting of ARHGEF2, NOD2 and RIPK2. Interacts (via CARD domain) with RIPK2 (via CARD domain). Interacts with ATG16L1. Interacts (via NACHT domain) with CARD9. Interacts with ANKRD17 (via N-terminus). Interacts with HSPA1A; the interaction enhances NOD2 stability. Interacts (via both CARD domains) with HSP90; the interaction enhances NOD2 stability. Interacts (via CARD domain) with SOCS3; the interaction promotes NOD2 degradation. Interacts (via CARD domain) with ERBBI2P; the interaction inhibits activation of NOD2. Interacts (via CARD domain) with CASP1; this interaction leads to IL1B processing. Also interacts with CASP4. Interacts with NLRP1; this interaction is enhanced in the presence of muramyl dipeptide (MDP) and leads to increased IL1B release. Interacts with MAPKBP1; the interaction is enhanced in the presence of muramyl dipeptide (MDP). Interacts with INAVA; the interaction takes place upon PRR stimulation. Interacts with ANKHD1, C10ORF67, CHMP5, DOCK7, ENTR1, KRT15, LDOC1, PPP1R12C, PPP2R3B, TRIM41 and VIM. Interacts with NLRP12; this interaction promotes degradation of NOD2 through the ubiquitin-proteasome pathway.

蛋白家族:

The ATG16L1-binding motif mediates interaction with ATG16L1.

Intramolecular interactions between the N-terminal moiety and the leucine-rich repeats (LRR) may be important for autoinhibition in the absence of activating signal. In the absence of LRRs, the protein becomes a constitutive activator of CASP1 cleavage and proIL1B processing.

Application: WB    Species: Human    Sample: peripheral blood T cells

Fig. 3. Upregulated expression of IRGM and autophagy in peripheral blood T cells of OLP patients. (A-B) Quantitative real-time RT-PCR results showed that IRGM mRNA levels increased in the peripheral blood T cells of OLP (n = 22, P = 0.001), non-erosive OLP (NEOLP, n = 12, P = 0.013) and erosive OLP (EOLP, n = 10, P = 0.033) when compared with that in healthy controls (n = 15), respectively. However, the relative levels of IRGM mRNA showed no significant difference between different clinical types of OLP (P > 0.05). (C-D) Similarly, the relative protein level of IRGM increased in peripheral blood T cells of EOLP (P < 0.001) and NEOLP (P < 0.001) when compared with that in healthy controls. (E-G) Meanwhile, the relative protein level of LC3B upregulated, whereas SQSTM1 and NOD2 protein expression decreased in peripheral blood T cells of all OLP patients (P < 0.05). There were significant differences of expression of LC3B (E, P < 0.001) and SQSTM1 protein (F, P < 0.001) between EOLP and NEOLP groups. The assay was performed in triplicate no less than 3 times. Data were shown as mean ± SEM. * P < 0.05, ** P < 0.01, ***P < 0.001, NS: P > 0.05, nonsignificantly.
