Sides the initially identified repair-associated genes, BRCA1 (25) and CYCB1;1 (28), and even the far more not too long ago identified genes (27), had been identified as SOG1 targets (Fig. four). These targets encode proteins that are essential for homologous recombination (HR) in plants and have already been assigned to unique Nucleoside Inhibitors medchemexpress repair steps in yeast, mammals, and/or plants, including early signaling events downstream in the MRN complicated (RAD17) (58), DNA end resection (GR1/COM1) (59), interhomolog pairing [HOP2 (60), MND1 (61, 62), and XRI1 (63)], strand invasion (RAD51 and RAD54) (9), and holiday junction formation/resolution [RFC1 (64, 65) and RecQl3 (66)]. In addition, SOG1 targets aspects that have an BAG3 Inhibitors MedChemExpress effect on HR, but play roles that happen to be much less well understood, such as NSE4A (67), AGO2 (68), and GMI1 (32). Apart from HR components, SOG1 targets DNA polymerases involved in DNA replication (POLD4) (69) and DNA repair [POLK (70) and POL2A (71)], also as genes involved in the production of deoxyribonucleotides [TSO2, RNR1 (72) and TK1a (73, 74)] which have been implicated in DNA repair (72, 75). Finally, numerous SOG1 targets stay uncharacterized, but are homologous to repair aspects in other organisms, or include domains indicating that they might have a role 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. four). Collectively, these analyses demonstrate that SOG1 quickly (inside 20 min) and straight targets key HR and DNA metabolism factors to facilitate DNA repair in a coordinated fashion. Constant with SOG1 only straight targeting eight in the DREM network, there are 33 TF genes, from 14 different TF families, that are directly regulated by SOG1, revealing the very first tier of a complex cascade of transcriptional responses initiated by SOG1 (Fig. four and SI Appendix, Fig. S11). Among these SOG1 targets are six other NAC TFs which might be very induced by -IR, highlighting the prominent role of this TF family members within the DNA damage response.
