Disease relevance of His2

  • His-1 and His-2: identification and chromosomal mapping of two commonly rearranged sites of viral integration in a myeloid leukemia [1].
  • No recombinants were observed between His-2 and Gin-1, a common site of provirus integration in Gross passage A MuLV-induced T-cell leukemias, in 131 backcross animals, suggesting that these loci are tightly linked [1].
 

High impact information on His2

  • The ORF encodes a protein with several features characteristic of regulatory factors, including two I repeats, two leucine zippers, and a single Cys-2/His-2 zinc finger [2].
  • Genetic mapping of these loci using interspecific backcross analysis assigned the His-1 locus to mouse chromosome 2 and the His-2 locus to mouse chromosome 19 [1].
  • This analysis revealed that Lvis1 maps between two previously identified viral insertion sites, His2 and Frat1, and does not cosegregate with known gene markers [3].
  • Replacements at two other positions (His-2 and Trp-3) completely negated immunocastration activity [4].
 

Anatomical context of His2

  • Probes from one integration site (His-1) defined a region that was rearranged in 3/52 cell lines, and probes from a second integration site (His-2) identified a rearrangement in 2/52 cell lines [1].
