SIRPɑ&PD1 Dual Effector Reporter Cell
CBP74154
I. Background | |
SIRP alpha protein, or Signal regulatory proteinalpha (SIRP-α), also known as Tyrosine protein phosphatase non-receptor type substrate 1, CD172a, Bit, and MyD-1, GenBank Accession No. NM_080792, a.a. 27-370, with C-terminal Avi and His tags, MW 40.3 kDa*. This SIRP alpha protein acts as a receptor for CD47; a.a. 27-370 correspond to the extracellular portion of SIRP-α. *Note: SIRP-α is heavily glycosylated, resulting in higher molecular weight.
The binding of Programmed Cell Death Protein 1 (PD-1), a receptor expressed on activated T-cells, to its ligands, PD-L1 and PD-L2, negatively regulates immune responses. PD-1 ligands are found on most cancers, and the PD-1:PD-L1/2 interaction inhibits T-cell activity and enables cancer cells to escape immune surveillance. The PD-1:PD-L1/2 pathway is also involved in regulating autoimmune responses, making these proteins promising therapeutic targets for a number of cancers, as well as multiple sclerosis, arthritis, lupus, and type I diabetes |
