Disease resistance protein of the TIR-NB-LRR-type. Part of the RPP5 locus that contains a cluster of several paralogous disease resistance (R) genes. Resistance proteins guard the plant against pathogens that contain an appropriate avirulence protein via an indirect interaction with this avirulence protein. That triggers a defense system including the hypersensitive response, which restricts the pathogen growth. Regulated by RNA silencing. Expression regulated by MOS1 at chromatin level. Negatively regulated at the transcript level by BON1.

The Toll/interleukin-1 receptor (TIR) homology domain is an intracellular signalling domain found in MyD88, interleukin 1 receptor and the Toll receptor. It contains three highly-conserved regions, and mediates protein-protein interactions between the Toll-like receptors (TLRs) and signal-transduction components. TIR-like motifs are also found in plant proteins thought to be involved in resistance to disease. When activated, TIR domains recruit cytoplasmic adaptor proteins MyD88 and TOLLIP (Toll interacting protein). In turn, these associate with various kinases to set off signalling cascades.

>PF01582 TIR: TIR domain; InterPro: IPR000157 In Drosophila melanogaster the Toll protein is involved in establishment of dorso-ventral polarity in the embryo
In addition, members of the Toll family play a key role in innate antibacterial and antifungal immunity in insects as well as in mammals. These proteins are type-I transmembrane receptors that share an intracellular 200 residue domain with the interleukin-1 receptor (IL-1R), the Toll/IL-1R homologous region (TIR). The similarity between Toll-like receptors (LTRs) and IL-1R is not restricted to sequence homology since these proteins also share a similar signalling pathway. They both induce the activation of a Rel type transcription factor via an adaptor protein and a protein kinase []. Interestingly, MyD88, a cytoplasmic adaptor protein found in mammals, contains a TIR domain associated to a DEATH domain (see IPR000488 from INTERPRO) [, , ]. Besides the mammalian and Drosophila melanogaster proteins, a TIR domain is also found in a number of plant proteins implicated in host defence []. As MyD88, these proteins are cytoplasmic. Site directed mutagenesis and deletion analysis have shown that the TIR domain is essential for Toll and IL-1R activities. Sequence analysis have revealed the presence of three highly conserved regions among the different members of the family: box 1 (FDAFISY), box 2 (GYKLC-RD-PG), and box 3 (a conserved W surrounded by basic residues). It has been proposed that boxes 1 and 2 are involved in the binding of proteins involved in signalling, whereas box 3 is primarily involved in directing localization of receptor, perhaps through interactions with cytoskeletal elements [].; GO: 0005515 protein binding, 0007165 signal transduction, 0005622 intracellular; PDB: 3J0A_A 2J67_B 3JRN_A 1FYV_A 1O77_D 1FYX_A 1FYW_A 3OZI_B 1T3G_B 2JS7_A ....
>PF08937 DUF1863: MTH538 TIR-like domain (DUF1863); InterPro: IPR015032 This protein adopts the flavodoxin fold, that is, five parallel beta-strands and four helical segments
The structure is a three-layer sandwich with alpha-1 and alpha-4 on one side of the beta-sheet, and alpha-2 and alpha-3 on the other side. Probable role in signal transduction as a phosphorylation-independent conformational switch protein []. This domain is similar to the TIR domain [].; PDB: 3HYN_A.
>PF08357 SEFIR: SEFIR domain; InterPro: IPR013568 This domain is found in IL17 receptors (IL17Rs, e
g. Q60943 from SWISSPROT) and SEF proteins (e.g. Q8QHJ9 from SWISSPROT). The latter are feedback inhibitors of FGF signalling and are also thought to be receptors. Due to its similarity to the TIR domain (IPR000157 from INTERPRO), the SEFIR region is thought to be involved in homotypic interactions with other SEFIR/TIR-domain-containing proteins. Thus, SEFs and IL17Rs may be involved in TOLL/IL1R-like signalling pathways [].
