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
PTCHD2 Antibody: PTCHD2, also known as DISP3, is the third of three known homologs of the D. melanogaster protein Dispatched. It is a multi-transmembrane protein containing two PTCH/DISP domains and is thought to be involved in the release of lipid-anchored secreted proteins. Like DISP1 and DISP2, DISP3 has been implicated in signaling pathways during embryogenesis, tissue regeneration, and carcinogenesis. It is highly expressed in Purkinje cells, hippocampal neurons, and retinal ganglion cells. Recently, it has been shown that PTCHD2 localizes within the endoplasmic reticulum and colocalizes with cholesterol, and given that its expression is regulated by thyroid hormone (T3), it has been suggested that DISP3 may be a link between thyroid hormone and cholesterol metabolism.
