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 central core of each mitogen-activated protein kinase(MAPK) pathway is a conserved cascade of 3 protein kinases: anactivated MAPK kinase kinase (MAPKKK) phosphorylates and activatesa specific MAPK kinase (MAPKK), which then activates a specificMAPK. While the ERK MAPKs are activated by mitogenic stimulation,the CSBP2 and JNK MAPKs are activated by environmental stressessuch as osmotic shock, UV irradiation, wound stress, andinflammatory factors. This gene encodes a MAPKKK, the MEKK4protein, also called MTK1. This protein contains a protein kinasecatalytic domain at the C terminus. The N-terminal nonkinase domainmay contain a regulatory domain. Expression of MEKK4 in mammaliancells activated the CSBP2 and JNK MAPK pathways, but not the ERKpathway. In vitro kinase studies indicated that recombinant MEKK4can specifically phosphorylate and activate PRKMK6 and SERK1,MAPKKs that activate CSBP2 and JNK, respectively but cannotphosphorylate PRKMK1, an MAPKK that activates ERKs. MEKK4 is amajor mediator of environmental stresses that activate the CSBP2MAPK pathway, and a minor mediator of the JNK pathway. Twoalternatively spliced transcripts encoding distinct isoforms havebeen described.
