SHH1, a homeodomain protein required for DNA methylation, as well as RDR2, RDM4, and chromatin remodeling factors, associate with RNA polymerase IV.
Los Angeles, United States. In Plos Genet, 2011
Data show that SHH1(AT1G15215), RDR2, CLASSY1, and RDM4 were co-purified with NRPD1(At1g63020), the largest subunit of Pol-IV.
Structure of the spliceosomal U4 snRNP core domain and its implication for snRNP biogenesis.
Cambridge, United Kingdom. In Nature, 2011
Four of the five major components of the spliceosome, U1, U2, U4 and U5 small nuclear ribonucleoproteins (snRNPs), contain seven Sm proteins (SmB/B', SmD1, SmD2, SmD3, SmE, SmF and SmG) in common.
RNA polymerase IV directs silencing of endogenous DNA.
Norwich, United Kingdom. In Science, 2005
results show that RNA polymerase IV (Pol IV, subunits NRPD1a and NRPD2) silences certain transposons and repetitive DNA in a short interfering RNA pathway involving RNA-dependent RNA polymerase 2 and Dicer-like 3(DCL3) [NRPD1a]
