Major histocompatibility complex, class I-related

MR1, major histocompatibility complex class I-related
This gene is thought to play a role in the regulation of myofibrillogenesis. Mutations in this gene have been associated with the movement disorder paroxysmal non-kinesigenic dyskinesia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2010] (from NCBI)

Functional Heterogeneity and Antimycobacterial Effects of Mouse Mucosal-Associated Invariant T Cells Specific for Riboflavin Metabolites.
New
Hoft et al., Melbourne, Australia. In J Immunol, 15 Aug 2015
Mucosal-associated invariant T (MAIT) cells have a semi-invariant TCR Vα-chain, and their optimal development is dependent upon commensal flora and expression of the nonpolymorphic MHC class I-like molecule MR1.

These cells recognize foreign/self-lipid presented by non-classical MHC molecules, such as CD1d, MR1, and CD1a.
Adoptive T Cell Therapy Targeting CD1 and MR1.
Review
New
Hirano et al., Toronto, Canada. In Front Immunol, Dec 2014
CD1 and MR1 are class I-like monomorphic molecules and their restricted T cells possess unique T cell receptor specificity against entirely different classes of antigens.

Review
New

Review
Impact
Cerundolo et al., Oxford, United Kingdom. In Annu Rev Immunol, 2013
In this review, we describe the most recent events in the field, with particular emphasis on (a) structural and functional aspects of lipid presentation by CD1 molecules, (b) the development of CD1d-restricted invariant natural killer T (iNKT) cells and transcription factors required for their differentiation, (c) the ability of iNKT cells to modulate innate and adaptive immune responses through their cross talk with lymphoid and myeloid cells, and (d) MR1-restricted and group I (CD1a, CD1b, and CD1c)-restricted T cells.
Mucosal-associated invariant T-cells: new players in anti-bacterial immunity.
Review
Willberg et al., Oxford, United Kingdom. In Front Immunol, 2013
MR1 has recently been shown to present an unstable pyrimidine intermediate derived from a biosynthetic precursor of riboflavin; riboflavin biosynthesis occurs in many bacteria but not in human beings.
Butyrophilin 3A1 binds phosphorylated antigens and stimulates human γδ T cells.

De Libero et al., Basel, Switzerland. In Nat Immunol, 2013
Human T cells that express a T cell antigen receptor (TCR) containing γ-chain variable region 9 and δ-chain variable region 2 (Vγ9Vδ2) recognize phosphorylated prenyl metabolites as antigens in the presence of antigen-presenting cells but independently of major histocompatibility complex (MHC), the MHC class I-related molecule MR1 and antigen-presenting CD1 molecules.

Impact
Lewinsohn et al., Portland, United States. In Nat Rev Microbiol, 2013
The semi-invariant antigen recognition receptor of MAIT cells detects the non-polymorphic antigen-presenting molecule major histocompatibility complex class I-related protein 1 (MR1), which can bind microorganism-derived riboflavin metabolites.
