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.

| Target Background | DLL4 is a type I membrane protein in the Delta/Serrate/Lag2 (DSL) family of Notch ligands. It activates NOTCH1 and NOTCH4, and plays a role in angiogenesis by negatively regulating endothelial cell proliferation and migration, as well as angiogenic sprouting. It is essential for retinal progenitor proliferation and is required for suppressing rod fates in late retinal progenitors, as well as for proper generation of other retinal cell types. Additionally, during spinal cord neurogenesis, it inhibits V2a interneuron fate. |
| Name | DLL4 |
|---|---|
| Function | Involved in the Notch signaling pathway as Notch ligand (PubMed:11134954). Activates NOTCH1 and NOTCH4. Involved in angiogenesis; negatively regulates endothelial cell proliferation and migration and angiogenic sprouting (PubMed:20616313). Essential for retinal progenitor proliferation. Required for suppressing rod fates in late retinal progenitors as well as for proper generation of other retinal cell types (By similarity). During spinal cord neurogenesis, inhibits V2a interneuron fate (PubMed:17728344). |
