Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

| Function | DNA-dependent metalloendopeptidase that mediates the proteolytic cleavage of covalent DNA-protein cross-links (DPCs) during DNA synthesis, thereby playing a key role in maintaining genomic integrity (PubMed:27852435, PubMed:27871366, PubMed:27871365, PubMed:32649882, PubMed:30893605, PubMed:36608669). DPCs are highly toxic DNA lesions that interfere with essential chromatin transactions, such as replication and transcription, and which are induced by reactive agents, such as UV light or formaldehyde (PubMed:27852435, PubMed:27871366, PubMed:27871365, PubMed:32649882, PubMed:36608669). Associates with the DNA replication machinery and specifically removes DPCs during DNA synthesis (PubMed:27852435, PubMed:27871366, PubMed:27871365, PubMed:32649882). Catalyzes proteolytic cleavage of the HMCES DNA-protein cross-link following unfolding by the BRIP1/FANCJ helicase (PubMed:36608669). Acts as a pleiotropic protease for DNA- binding proteins cross-linked with DNA, such as TOP1, TOP2A, histones H3 and H4 (PubMed:27871366). Mediates degradation of DPCs that are not ubiquitinated, while it is not able to degrade ubiquitinated DPCs (By similarity). SPRTN activation requires polymerase collision with DPCs followed by helicase bypass of DPCs (By similarity). Involved in recruitment of VCP/p97 to sites of DNA damage (PubMed:22902628, PubMed:23042605, PubMed:23042607, PubMed:32152270). Also acts as an activator of CHEK1 during normal DNA replication by mediating proteolytic cleavage of CHEK1, thereby promoting CHEK1 removal from chromatin and subsequent activation (PubMed:31316063). Does not activate CHEK1 in response to DNA damage (PubMed:31316063). May also act as a 'reader' of ubiquitinated PCNA: recruited to sites of UV damage and interacts with ubiquitinated PCNA and RAD18, the E3 ubiquitin ligase that monoubiquitinates PCNA (PubMed:22681887, PubMed:22894931, PubMed:22902628, PubMed:22987070). Facilitates chromatin association of RAD18 and is required for efficient PCNA monoubiquitination, promoting a feed-forward loop to enhance PCNA ubiquitination and translesion DNA synthesis (PubMed:22681887). |
| Cellular Location | Nucleus. Chromosome. Note=Localizes to sites of UV damage via the PIP-box (PubMed:22894931, PubMed:23042605). Recruited to stalled replication forks at sites of replication stress following deubiquitination (PubMed:22894931, PubMed:23042605, PubMed:22987070, PubMed:27871365, PubMed:32649882). CHEK1 stimulates recruitment to chromatin (PubMed:31316063). |
