Download as PDF. Watch Recorded Presentation Jane Lamerdin, Ph.D. … This CD47/SIRP alpha binding assay can be run in a 96- or 384-well low volume white plate (20 µL final). As described here, samples or standards are dispensed directly into the assay plate, and the tagged CD47 & SIRP alpha protein are then added, followed by the dispensing of the HTRF reagents. The Targeting the CD47-SIRPA Axis in Oncology: Analytical Tool is continuously updated according to twelve of the world's most influential meetings in oncology (AACR, ASCO, ASGCT, ASH, CMIT, EHA, EORTC-NCI-AACR, ESMO, SITC and BIO (International, Europe and Asia). If you are not able to attend any of the conferences in person, this Analytical CD47 is a transmembrane protein expressed the surface of many cells in the body.

TTI-621 (SIRPaFc) is a fully humanrecombinant fusionproteinthatblocksthe CD47–SIRPa CD47/SIRPα, AN IMMUNE CHECKPOINT FORINNATE IMMUNE SYSTEM. Among cells of the myeloid lineage, macrophage has prominent potentials as the mediator of anti-cancer therapeutics based on its robust phagocytosis ability [8, 9]. CD47, known as an integrin-associated protein, was first identified as a transmembrane protein from red blood cells (RBC) . Has a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins. Plays an important role in memory formation and synaptic plasticity in the hippocampus (By similarity).

Acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. Se hela listan på academic.oup.com SIRPA is a transmembrane protein expressed in macro-phages, myeloid cells, and neurons, and it contains three immunoglobulin (Ig)-like domains within the extracellular region.

Signal regulatory protein α (SIRPα) is a regulatory membrane glycoprotein from SIRP family expressed mainly by myeloid cells and also by stem cells or neurons. SIRPα acts as inhibitory receptor and interacts with a broadly expressed transmembrane protein CD47 also called the "don´t eat me" signal.
