SUMMARY PARAGRAPH for THP2

THP2 encodes a subunit of the THO complex, a nuclear complex comprised of Hpr1p, Mft1p, Rlr1p, and Thp2p, that is involved in transcription elongation by RNA polymerase II (1). Null mutations of any of the four THO complex genes are viable and exhibit similar phenotypes: a defect in transcription elongation, an increase in mitotic recombination between direct repeats (1), and defects in mRNA export (4, 2). The THO complex, along with Sub2p, Yra1p, and Tex1p, forms the transcription export (TREX) complex, conserved from yeast to metazoans and involved in the coupling of transcription to the export of the resulting mRNA (2).
