This domain is found in RNA-dependent RNA polymerase 2 (RDR2) from Arabidopsis thaliana and related proteins. RDR2 is involved in the production of small interfering RNAs (siRNAs). It binds to single-stranded RNA (ssRNA), engages ssRNAs longer than 7 nucleotides and initiates internal to their 3' ends [1]. RDR2 is non-functional in the absence of associated Pol IV [2]. The domain represented by this entry adopts a beta-barrel structure with significant similarity to known PH domains [1].	Domain
