High impact information on RPL19B

  • Yeast cells containing disruption of either RPL19A or RPL19B formed smaller colonies than wild-type strains; however, simultaneous deletion of both genes is lethal [1].
  • RPL19B is also closely linked to a mitochondrial ADP/ATP carrier protein gene AAC2 [1].
  • The nucleotide sequence of the gene, RPL19B, was determined [1].
  • The coding regions of the two yeast genes, RPL19A and RPL19B, differ in only 34 nucleotides, none of which lead to changes in the amino-acid sequences of the predicted protein of 189 amino acids [1].
