Background
CD172a (SIRPα) and CD172b (SIRPβ1) are paired immunoglobulin-superfamily transmembrane glycoproteins that regulate myeloid-cell activation: CD172a binds CD47 to deliver inhibitory “don’t-eat-me” signals via SHP-1/2 phosphatases, controlling phagocytosis and dendritic-cell homeostasis, whereas CD172b lacks CD47 affinity and instead partners with the adaptor DAP12 to recruit SYK kinase and provide activating cues during innate immune responses.
