The bovine TRBC genes. (A) Predicted amino acid sequences of products of the TRBC1, 2 and 3 genes. The regions encoded by the 4 exons and the boundaries between the predicted extra-cellular (EX), hinge (H), trans-membrane (TM) and cytoplasmic (CY) domains have been marked. The sequence for a 7 amino acid section of TRBC2 can not be predicted due to absence of nucleotide sequence for exon 2 (represented by dots). (B) Pairwise percentage identity of nucleotide sequences between the exons, introns and 3'UTR of the 3 TRBC genes. Some pairwise comparisons have been omitted due to a region of undetermined sequence spanning the 1st intron, 2nd exon and 2nd intron of TRBC2.
