Encodes a component of Replication Protein A. Component of transcriptional gene silencing which does not affect endogenous small RNA accumulation nor DNA methylation. Localized in the nucleus. Involved in DNA repair. Interacts physically with ROS1.
At2g24490 is the RPA2 gene, which plays an essential role in the maintenance of transcriptional gene silencing at specific loci in a DNA-methylation-independent manner.
