TRD1 Encodes the Catalytic Subunit of the RNase H2 Complex.

(A) Intron-exon organization of TRD1. Black and gray boxes represent exons and untranslated regions, respectively. The position of the mutated base pair (trd1-1) and T-DNA insertion site (trd1-2) are indicated.

(B) Sequence alignment of the RNase H2 subunit A from different species highlighting the conserved position of the Gly residue (indicated by a star). Mm, Mus musculus; Hs, Homo sapiens; Os, Oryza sativa; Zm, Zea mays; At, Arabidopsis thaliana; Sc, Saccharomyces cerevisiae.
