Sides the initially identified repair-associated genes, BRCA1 (25) and CYCB1;1 (28), or even the much more lately identified genes (27), have been identified as SOG1 targets (Fig. four). These targets encode proteins that are PNU-177864 Autophagy essential for homologous recombination (HR) in plants and have already been assigned to distinctive repair steps in yeast, mammals, and/or plants, such as early signaling events downstream in the MRN complex (RAD17) (58), DNA finish resection (GR1/COM1) (59), interhomolog pairing [HOP2 (60), MND1 (61, 62), and XRI1 (63)], strand invasion (RAD51 and RAD54) (9), and vacation junction formation/resolution [RFC1 (64, 65) and RecQl3 (66)]. Also, SOG1 targets variables that affect HR, but play roles which are much less well understood, including NSE4A (67), AGO2 (68), and GMI1 (32). In addition to HR aspects, SOG1 targets DNA polymerases involved in DNA replication (POLD4) (69) and DNA repair [POLK (70) and POL2A (71)], as well as genes involved within the production of deoxyribonucleotides [TSO2, RNR1 (72) and TK1a (73, 74)] which have been implicated in DNA repair (72, 75). Ultimately, numerous SOG1 targets stay uncharacterized, but are homologous to repair components in other organisms, or contain domains indicating that they could have a part in DNA repair, including AT1G80850, a gene encoding a DNA glycosylase (76), AT4G02110, a gene encoding a BRCA1 C-terminal domain protein (77), and FANCJA, a gene homologous to a mammalian Fanconi anemia group I-like element involved in HR repair (78) (Fig. 4). With each other, these analyses demonstrate that SOG1 rapidly (inside 20 min) and directly targets crucial HR and DNA metabolism aspects to facilitate DNA repair inside a coordinated style. Constant with SOG1 only straight targeting 8 in the DREM network, you can find 33 TF genes, from 14 diverse TF households, which are directly regulated by SOG1, revealing the initial tier of a complicated cascade of transcriptional responses initiated by SOG1 (Fig. 4 and SI Appendix, Fig. S11). Amongst these SOG1 targets are six other NAC TFs that happen to be highly induced by -IR, highlighting the prominent part of this TF family members within the DNA damage response.
