Function
DBP5_YEAST ATP-dependent RNA helicase associated with the nuclear pore complex and essential for mRNA export from the nucleus. May participate in a terminal step of mRNA export through the removal of proteins that accompany mRNA through the nucleopore complex. Contributes to the blocking of bulk poly(A)+ mRNA export in ethanol-stressed cells. May also be involved in early transcription.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]
