CD7, also known as Leu-9, is an approximately 40 kDa glycosylated and palmitoylated transmembrane protein in the immunoglobulin superfamily. Mature human CD7 consists of a 155 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 39 aa cytoplasmic domain. Within the ECD, human CD7 shares 43% and 41% aa sequence identity with mouse and rat CD7, respectively. CD7 is expressed on T cells, NK cells, myeloid progenitor cells, and CD19+ B progenitor cells. Among CD8+ T cells, the CD7-bright population preferentially contains naïve and memory cells, while more weak expressors are primarily effector cells. It also enhances integrin-mediated adhesion of these cells to Fibronectin, ICAM-1, and VCAM-1 . CD7 additionally mediates the Galectin-1 induced apoptosis of T cells and facilitates the fusion of HIV-1 with target cells.
