Target Background | The T-cell surface glycoproteins CD3E and CD3D, also called CD3 epsilon and CD3 delta chain, are single-pass type I membrane proteins. When antigen presenting cells (APCs) activate the T-cell receptor (TCR), TCR signals are transmitted by the CD3 chains CD3D, CD3E, CD3G, and CD3Z. All CD3 chains have immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain. |
