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
Mouse Interleukin-21 (m-IL-21), expressed by activated CD4(+) T cells, is the newest member of the common gamma-chain family of cytokines, which also includes IL-2, IL-4, IL-7, IL-9, and IL-13. Its private receptor, IL-21R, is expressed on T, B, and NK cells. Within the B cell lineage, IL-21 regulates IgG1 production and cooperates with IL-4 for the production of multiple Ab classes in vivo. IL-21R has been shown to activate the Janus kinase/signal transducers and activators of transcription signaling pathways upon ligand binding. Initial studies have demonstrated that IL-21 has pleiotropic effects on the proliferation, the differentiation, and the effector functions of B, T, natural killer, and dendritic cells. Recombinant mouse IL-21, produced in E.coli, is a single, non-glycosylated polypeptide chain containing 130 amino acids and having a total molecular mass of 15,095 Daltons.
