Fig. 4. Loss of Vps20p or Vta1p causes only slightly altered kinetics of ${alpha}$ -factor internalisation. Wild-type (RH1800) and vps20 ${Delta}$ (AMY174), and wild-type (AMY165) and vta1 ${Delta}$ (AMY162) cells were grown to early exponential phase and assayed for [³⁵S] ${alpha}$ -factor internalisation at 30°C. After addition of the [³⁵S] ${alpha}$ -factor, samples were taken in duplicate at various time points and washed in either phosphate buffer pH 6 (removes unbound [³⁵S] ${alpha}$ -factor) or citrate buffer pH 1 (removes bound but non-internalised [³⁵S] ${alpha}$ -factor). Shown is the internalised ${alpha}$ -factor as a percentage of the bound ${alpha}$ -factor at each time point.
