T-Cell Antigen CD7 (CD7) Protein

Background

The CD7 molecule, also known as GP40 or Tp40, is a member of the immunoglobulin superfamily and is primarily expressed on thymocytes and mature T cells. This 40 kDa glycoprotein plays a significant role in T cell interactions and signaling. CD7 is a crucial component in the immune response, involved in the regulation and activation of T cells, and is also present on natural killer (NK) cells. It was initially identified due to its consistent expression on T cells and its involvement in various immune functions.
