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 Ras pathway is a critical si gnal transduction cascade involved in regulating cellular proliferation, differentiation, su rvival, and oncogenic transformation. Members of the Raf serine/threonine kinase family are key intermediates in this cascade, functioning to relay signals from activated Ras to the downstream protein kinases M EK and ERK (Marshall, 1996). Previous studies have shown that phosphorylation is required for Raf-1 ac tivation (Dhillon and Kolch, 2002; Chong et al., 2003). Recent work has demonstrated that phosphorylation al so regulates the downregulation of Raf (Dougherty et al., 2005) with two sites participating: Ser 301 and Ser 642 .
