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
CRB1 Antibody: CRB1 (Crumbs homolog 1) plays a role in photoreceptor morphogenesis in the retina. It may maintain cell polarization and adhesion. CRB1 is similar to the Drosophila crumbs protein and localizes to the inner segment of mammalian photoreceptors. The first identified human homolog, CRB1, is expressed in retina and some parts of the brain, leaving room for another homolog to function in epithelial tissues. Mutations in this gene are associated with a severe form of retinitis pigmentosa, RP12, and with Leber congenital amaurosis.
