Interacts with the zeta DNA polymerase complex; interacts (via the N-terminus) with the accessory subunit PolZ2/Rev7 and also interacts with the catalytic component PolZ1, however the interaction with PolZ1 is likely via PolZ2.

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
dsDNA 3'-exonuclease activity of Rrp1 is more efficient in purine-rich regions than in pyrimidine-rich regions. The base occupying the penultimate position in the 3'-terminal dinucleotides may be important in determining the relative efficiency of bond cleavage by Rrp1. These results suggest that the sequence specificity of Rrp1-catalysed phosphodiester backbone cleavage is determined by the specific DNA-protein interactions in the enzyme active site.
The 3'-phosphodiesterase and 3'-phosphatase activities of the Rrp1 enzyme have been demonstrated and characterised.
The nuclease activities of Rrp1 include AP-endonuclease, phosphodiesterase, phosphatase and 3'-exonuclease. Unique N-terminal region is associated with strand transfer and ssDNA renaturation activities indicating a possible role in homologous recombination.
Site-directed mutagenesis of Rrp1 identifies Glu-461 as a residue that appears to be essential for the nuclease function and Lys-463 and Thr-462 influence the substrate specificity of the nuclease.
