Human inhibitory receptors Ig-like transcript 2 (ILT2) and ILT4 compete with CD8 for MHC class I binding and bind preferentially to HLA-G
Mitsunori Shiroishi,Kouhei Tsumoto,Kimie Amano,Yasuo Shirakihara,Marco Colonna,Veronique M. Braud,David S.J. Allan,Azure T Makadzange,Sarah Rowland-Jones,Benjamin E. Willcox,E. Yvonne Jones,P. Anton van der Merwe,Izumi Kumagai,Katsumi Maenaka,Katsumi Maenaka +14 more
TL;DR: ILT2 and ILT4 effectively compete with CD8 for MHCI binding, raising the possibility that ILT2 modulates CD8+ T cell activation by blocking the CD8 binding as well as by recruiting inhibitory molecules through its immunoreceptor tyrosine-based inhibitory receptor motif.
Journal ArticleDOI
VHL-box and SOCS-box domains determine binding specificity for Cul2-Rbx1 and Cul5-Rbx2 modules of ubiquitin ligases
Takumi Kamura,Katsumi Maenaka,Shuhei Kotoshiba,Masaki Matsumoto,Daisuke Kohda,Ronald C. Conaway,Ronald C. Conaway,Joan W. Conaway,Joan W. Conaway,Keiichi I. Nakayama +9 more
TL;DR: Domain-swapping analyses showed that the specificity of interaction of VHL-box and SOCS-box proteins with Cullin-Rbx modules is determined by the Cul2 and Cul5 boxes, respectively, which suggest that the functions of the Cul1-rbx1 and Cul2-R bx2 modules are distinct.
Journal ArticleDOI
Structural basis for recognition of the nonclassical MHC molecule HLA-G by the leukocyte Ig-like receptor B2 (LILRB2/LIR2/ILT4/CD85d)
Mitsunori Shiroishi,Kimiko Kuroki,Linda Rasubala,Kouhei Tsumoto,Izumi Kumagai,Eiji Kurimoto,Koichi Kato,Daisuke Kohda,Katsumi Maenaka +8 more
TL;DR: The results suggest that subtle structural differences between LILRB family members cause the distinct binding specificities to various forms of HLA-G and other MHCIs, which may in turn regulate immune suppression.
Journal ArticleDOI
Cutting Edge: Allele-specific and peptide-dependent interactions between KIR3DL1 and HLA-A and HLA-B.
Hathairat Thananchai,Geraldine M. Gillespie,Maureen P. Martin,Arman Bashirova,Nobuyo Yawata,Makoto Yawata,Philippa Easterbrook,Daniel W. McVicar,Katsumi Maenaka,Peter Parham,Mary Carrington,Tao Dong,Sarah Rowland-Jones +12 more
TL;DR: This study shows that HLA-A*2402 is a ligand for KIR3DL1 and demonstrates how the binding of KIR 3DL1 to Bw4+ ligands depends upon the bound peptide as well as HLA and KIR2DL1 polymorphism.
Journal ArticleDOI
Molecular basis of selective mitochondrial fusion by heterotypic action between OPA1 and cardiolipin.
Tadato Ban,Takaya Ishihara,Hiroto Kohno,Shotaro Saita,Shotaro Saita,Ayaka Ichimura,Katsumi Maenaka,Toshihiko Oka,Katsuyoshi Mihara,Katsuyoshi Mihara,Naotada Ishihara +10 more
TL;DR: It is shown that L-OPA1 and cardiolipin (CL) cooperate in heterotypic mitochondrial IM fusion, and multiple OPA1 functions are modulated by local CL conditions for regulation of mitochondrial morphology and quality control.
