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.

Background
The LIN-12/Notch family of transmembrane receptors plays a central role in development by regulating cell fate decisions (1). Ligands for Notch include JAG1, JAG2 and Delta. JAG1 is one of the DSL (Delta, Serrate, Lag2) transmembrane proteins that can activate Notch. It is involved in mammalian cardiovascular development and in cell-fate decisions during hematopoiesis (1,2). JAG1 is widely expressed in adult and fetal tissues and the mutation of the JAG1 gene is associated with Familial Tetrology of Fallot (3). JAG1 expression is associated with prostate cancer metastasis and is up-regulated in cervical squamous cell carcinoma (4,5).
