High impact information on PFA3

  • Here we demonstrate that the DHHC-CRD proteins Pfa3p (protein fatty acyltransferase 3, encoded by YNL326c) and Swf1p are important for vacuole fusion [1].
  • The vacuolar DHHC-CRD protein Pfa3p is a protein acyltransferase for Vac8p [1].
  • Cells lacking Pfa3p had fragmented vacuoles when stressed, and cells lacking both Pfa3p and Swf1p had fragmented vacuoles under normal growth conditions [1].
  • Interestingly, Pfa3 is required for the vacuolar localization of not only an SH4 domain that is targeted by myristate/palmitate (as in Vac8) but also one that is targeted by a myristate/basic stretch (as in Src) [2].
  • Moreover, both the DHHC-CRD acyltransferase Pfa3 and Ykt6 are involved in palmitoylation at the vacuole Here, we present and discuss methods to probe for protein palmitoylation at vacuoles [3].
