Antigen recognition by alphabeta T lymphocytes is mediated via the multisubunit TCR complex consisting of invariant CD3gamma,delta,epsilon and zeta chains associated with clonotypic TCRalpha and beta molecules. Charged amino acids located centrally within the TCRalpha transmembrane region are necessary and sufficient for assembly with the CD3deltaepsilon(More)
During neural development of Drosophila melanogaster, Glial Cells Missing (GCM), functions as a binary switch that promotes glial cell fate while simultaneously inhibiting the neuronal fate. Sequence similarities between GCM and the recently identified mouse protein mGCMa are strictly limited to the aminoterminal DNA-binding domain. Here we show that mGCMa(More)
A key question yet to be resolved concerns the structure and function relationship of the TCR complex. How does antigen recognition by the TCR-alphabeta chains result in the activation of distinct signal transduction pathways by the CD3-gammadeltaepsilon/zeta complex? To investigate which part of the TCR-beta chain is involved in TCR signaling, we exchanged(More)
Correct assembly of all TCR complex polypeptides is essential for its cell surface expression and function. The transmembrane region of the TCRalpha chain is highly conserved and to gain insight into the structural and functional role of these residues, single amino acid substitutions were introduced and surface expression and signaling ability studied in T(More)
