The product of the YCR105 gene located on the chromosome III from Saccharomyces cerevisiae presents homologies to ATP-dependent permeases.

During the systematic sequencing of chromosome III from Saccharomyces cerevisiae, carried out by a network of laboratories sponsored by the Commission of the European Community, we have identified the open reading frame YCR105 located on fragment J11D from the circular derivative of chromosome III in strain XJ24-24a (Palzkill et al., 1986). YCR105 is immediately centromere proximal to the PGK gene (opposite strand) on the right arm of chromosome III about 20 kb from the centromere.
