タンパク質の説明:
Members of the Toll-like receptor (TLR) family, named for the closely related Toll receptor in Drosophila, play a pivotal role in innate immune responses (1-3). TLRs recognize conserved motifs found in various pathogens and mediate defense responses. Triggering of the TLR pathway leads to the activation of NF-κB and subsequent regulation of immune and inflammatory genes. The TLRs and members of the IL-1 receptor family share a conserved stretch of approximately 200 amino acids known as the TIR domain. Upon activation, TLRs associate with a number of cytoplasmic adaptor proteins containing TIR domains including MyD88 (myeloid differentiation factor), MAL/TIRAP (MyD88-adaptor-like/TIR-associated protein), TRIF (Toll-receptor-associated activator of interferon), and TRAM (Toll-receptor-associated molecule). This association leads to the recruitment and activation of IRAK1 and IRAK4, which form a complex with TRAF6 to activate TAK1 and IKK. Activation of IKK leads to the degradation of IκB that normally maintains NF-κB inactivity by sequestering it in the cytoplasm.

研究背景

機能:

Cooperates with LY96 to mediate the innate immune response to bacterial lipoproteins and other microbial cell wall components. Cooperates with TLR1 or TLR6 to mediate the innate immune response to bacterial lipoproteins or lipopeptides. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. May also activate immune cells and promote apoptosis in response to the lipid moiety of lipoproteins. Recognizes mycoplasmal macrophage-activating lipopeptide-2kD (MALP-2), soluble tuberculosis factor (STF), phenol-soluble modulin (PSM) and B.burgdorferi outer surface protein A lipoprotein (OspA-L) cooperatively with TLR6. Stimulation of monocytes in vitro with M.tuberculosis PstS1 induces p38 MAPK and ERK1/2 activation primarily via this receptor, but also partially via TLR4. MAPK activation in response to bacterial peptidoglycan also occurs via this receptor. Acts as a receptor for M.tuberculosis lipoproteins LprA, LprG, LpqH and PstS1, some lipoproteins are dependent on other coreceptors (TLR1, CD14 and/or CD36); the lipoproteins act as agonists to modulate antigen presenting cell functions in response to the pathogen. M.tuberculosis HSP70 (dnaK) but not HSP65 (groEL-2) acts via this protein to stimulate NF-kappa-B expression. Recognizes M.tuberculosis major T-antigen EsxA (ESAT-6) which inhibits downstream MYD88-dependent signaling (shown in mouse) (By similarity). Forms activation clusters composed of several receptors depending on the ligand, these clusters trigger signaling from the cell surface and subsequently are targeted to the Golgi in a lipid-raft dependent pathway. Forms the cluster TLR2:TLR6:CD14:CD36 in response to diacylated lipopeptides and TLR2:TLR1:CD14 in response to triacylated lipopeptides. Required for normal uptake of M.tuberculosis, a process that is inhibited by M.tuberculosis LppM (By similarity).

PTMs:

Glycosylation of Asn-442 is critical for secretion of the N-terminal ectodomain of TLR2.

Ubiquitinated at Lys-754 by PPP1R11, leading to its degradation. Deubiquitinated by USP2 (By similarity).

細胞の位置付け:

Membrane>Single-pass type I membrane protein. Cytoplasmic vesicle>Phagosome membrane>Single-pass type I membrane protein. Membrane raft.
Note: Does not reside in lipid rafts before stimulation but accumulates increasingly in the raft upon the presence of the microbial ligand. In response to diacylated lipoproteins, TLR2:TLR6 heterodimers are recruited in lipid rafts, this recruitment determines the intracellular targeting to the Golgi apparatus. Triacylated lipoproteins induce the same mechanism for TLR2:TLR1 heterodimers.

サブユニット構造:

Interacts with LY96, TLR1 and TLR6 (via extracellular domain). TLR2 seems to exist in heterodimers with either TLR1 or TLR6 before stimulation by the ligand. The heterodimers form bigger oligomers in response to their corresponding ligands as well as further heterotypic associations with other receptors such as CD14 and/or CD36. Binds MYD88 (via TIR domain). Interacts with TICAM1. Interacts with CNPY3 (By similarity). Interacts with ATG16L1. Interacts with PPP1R11 (By similarity). Interacts with TICAM2.

(Microbial infection) Interacts with M.tuberculosis EsxA.

(Microbial infection) Interacts with M.bovis MPB83.

(Microbial infection) Interacts with Staphylococcus aureus protein SSL5.

タンパク質ファミリー:

Ester-bound lipid substrates are bound through a crevice formed between the LRR 11 and LRR 12.

The ATG16L1-binding motif mediates interaction with ATG16L1.

The TIR domain mediates NAD(+) hydrolase (NADase) activity. Self-association of TIR domains is required for NADase activity.

Belongs to the Toll-like receptor family.
