CD69 (also known as CLEC2C, VEA, AIM, EA1, MLR3, gp34/28) is a type II transmembrane C-type lectin glycoprotein that forms a ~60 kDa disulfide-linked homodimer. The mature human protein consists of a 40-amino-acid cytoplasmic domain, a 21-amino-acid transmembrane segment, and a 138-amino-acid extracellular domain containing a C-type lectin domain, sharing ~57% sequence identity with mouse and rat CD69. CD69 is rapidly upregulated on activated immune cells, including CD4⁺ and CD8⁺ T cells, NK cells, NKT cells, γδ T cells, B cells, dendritic cells, neutrophils, and a subset of thymocytes and platelets. It functions as an early activation marker, mediates T cell differentiation, immune cell trafficking, and homing of CD4⁺ T cells and plasmablasts to bone marrow, while inhibiting migration of dermal dendritic cells to lymph nodes.
