General Information

  • Identifier IPR040017
  • Description Exportin-T

Abstract

Exportin-T mediates the nuclear export of aminoacylated tRNAs [ 1 ]. Its budding yeast homologue, known as Los1, is involved in nuclear export of pre-tRNA and in re-export of mature tRNAs [ 2 ]. It binds to RanGTP and mature tRNAs cooperatively to form a nuclear export complex [ 3 ].
