Structure and evolution of a member of a new subfamily of GTP-binding proteins mapping to the human MHC class I region.
[No authors listed]
摘要
A gene coding for a putative GTP-binding protein, MMR1, has been localized on band C of the murine Chr 17 within or close to the MHC (Denizot et al. 1992). Its human homolog, HSR1, localized to the human MHC class I region, is described in this paper. Its sequence, compared with MMR1, shows that the conceptual proteins encoded by these genes are highly homologous and have thus been subjected to high constraints during evolution. Furthermore, a detailed databank search with HSR1 leads to the characterization of a new subfamily of GTP-binding proteins, of which HSR1 and MMR1 are the only eukaryotic members. The precise localization of HSR1 within the human MHC class I region is also presented.
