NPL3

Saccharomyces cerevisiae

RNA-binding guard protein; promotes transcription elongation and regulates termination; binds eIF4G to repress translation initiation; role in nuclear export of poly(A) mRNA and in pre-mRNA splicing; links chromatin modification to mRNA processing; prevents R-loop-mediated genome instability and replication stress; binds TERRA, stabilizing R-loops at short telomeres; phosphorylated by Sky1p to promote shuttling and mRNA dissociation; protein abundance increases during DNA replication stress
