وصف
Cytotoxic T-lymphocyte protein 4, also known as CTLA4 and CD152, is a single-pass type I membrane protein. CTLA4 is a member of the immunoglobulin superfamily, which is expressed on the surface of Helper T cells and it is also found in regulatory T cells. CTLA4 is similar to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells.
