The T cell antigen receptor (TCR) and pre-TCR complexes are comprised of multiple signal-transducing subunits (CD3, CD3, CD3, and ) that each contain one or more copies of a semiconserved functional motif, the immunoreceptor tyrosine-based activation motif (ITAM). initiate a broad range of mature T cell responses. Signaling by the TCR and its precursor, the… Continue reading The T cell antigen receptor (TCR) and pre-TCR complexes are comprised
