This domain is found C-terminal in the RNA-dependent RNA polymerases such as RDR1/2/3/4/5/6 and related proteins. This domain folds into array of alpha helices and it is known as head [1]. The head domain was proposed to interact with incoming template RNA, helping guide the RNA to the active site [1].	Domain

This RRM domain is found N-terminal in the RNA-dependent RNA polymerase 1 and 2 (RDR1, RDR2) from Arabidopsis thaliana and related plant proteins. RDR1 is involved in antiviral silencing, amplifying silencing signals during viral infections [1]. In Arabidopsis, RDR2 physically interacts with DNA-dependent NUCLEAR RNA POLYMERASE IV (Pol IV) and their activities are tightly coupled, with Pol IV transcriptional arrest, induced by the nontemplate DNA strand, somehow enabling RDR2 to engage Pol IV transcripts and generate double-stranded RNAs [2].	Domain
A	PF24823	RDR2 PH-like domain (PH_RDR2)	RDR2 PH-like domain	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 ...	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
