High impact information on Bat1a

  • As RT1.L3 maps closely to the deletion in the mutant haplotype lm1, the RT1.L family can be located in the class I region extending from Bat1 to Pou5f1 [1].
  • Homology searches suggest a transition in the rat sequence with a proximal stretch containing Nfkbil1, ATP6G, and Bat1, which is homologous to the mouse H2-D region, and a more-distal stretch, which contains the class I gene and has many similarities to mouse H2-Q region sequences [2].
  • To determine whether the rat possesses an H2-D orthologue, we sequenced a cosmid clone that contains rat Bat1 and an adjacent class I gene, RT1.46 (l) [2].
  • The present study was undertaken to map these regions cytogenetically by several different approaches using cosmids specific for the Rps 18, Hspa1 and Bat1 genes [3].
