Gene Information

rabbit ... TopBP1(11073)

Immunogen

The epitope recognized by PLA0030 maps to a region between residue 1400 and the C-terminus (residue 1435) of human Topoisomerase (DNA) II Binding Protein 1 using the numbering given in entry NP_008958.1 (GeneID 11073).

Physical form

Tris-citrate/phosphate buffer, pH 7 to 8 containing 0.09% sodium azide

Other Notes

Topoisomerases regulate topological states of DNA. DNA topoisomerase II-binding protein 1 (TopBP1) is a protein that interacts with the C-terminal region of topoisomerase II beta (Topo II beta). TopBP1 function has been found to be important to various aspects of cellular growth control such as DNA replication, the DNA damage checkpoint, and cell survival. TopBP1 interacts with several proteins through its BRCA1 C-terminal (BRCT) motifs. TopBP1 interacts and inhibits E2F1 transcriptional activity through an Rb-independent mechanism that involves recruitment of the SWI/SNF chromatin-remodeling complex proteins Brg1 and Brm.

Interactions with the immune system may lead tumorigenic cells into dormancy. However, the underlying molecular mechanism is poorly understood. Using a 3D fibrin gel model, we show that IFN-γ induces tumour-repopulating cells (TRCs) to enter dormancy through an indolamine 2,3-dioxygenase

Despite the clinical successes fostered by immune checkpoint inhibitors, mechanisms underlying PD-1 upregulation in tumor-infiltrating T cells remain an enigma. Here, we show that tumor-repopulating cells (TRCs) drive PD-1 upregulation in CD8+ T cells through a transcellular kynurenine (Kyn)-aryl hydrocarbon receptor (AhR)
