Beta tubulin III, also known as Tuj-1, is a class III member of the beta tubulin protein family. Beta tubulins are one of two structural components that form our microtubule network.

53BP1 (p53 binding protein 1) was originally thought to be an enhancer for p53 transcriptional, but later studies have demonstrated that it is actually a substrate for ataxia telangiectasia mutated (ATM). 53BP1 is a classic late DNA damage response (DDR) marker that is present during the cell cycle phases of telophase and cytokinesis (within mitotic mammalian cells).

The 53BP1 (p53 binding protein 1) was initially believed to be a p53 transcriptional enhancing partner, but it has now been established as an ataxia telangiectasia mutated (ATM) substrate. As a late DNA damage response (DDR) marker, 53BP1 appears during the telophase and cytokinesis phase of mitotic mammalian cells¹.

PCNA antibodies are useful biomarkers in DNA repair studies. PCNA is one of several proteins essential for the completion of nucleotide excision repair, a multi-stage process involving 20 - 30 proteins, and an important factor in repairing damage and mutations to the DNA helical structure.

We at Novus Biologicals have over 230 products in our antibody catalog devoted to nucleotide excision repair. NER is a multi-stage sequential process involving over 30 proteins, all of which have been widely studied. Being the primary method to repair DNA damage caused by agents ranging from UV radiation to chemotherapy drugs, our NER antibody database is widely used by cancer research groups.
