Remark 999 | SEQUENCE Author states the sequence of the BM3.3 TCR has never been deposited in any database, ...SEQUENCE Author states the sequence of the BM3.3 TCR has never been deposited in any database, however it has been published in the following paper: Couez D, Malissen M, Buferne M, Schmitt-Verhulst AM, Malissen B. (1991) Each of the two productive T cell receptor alpha-gene rearrangements found in both the A10 and BM 3.3 T cell clones give rise to an alpha chain which can contribute to the constitution of a surface-expressed alpha beta dimer. Int Immunol. 3(7):719-29. Moreover, TCR sequences are the result of V,J and C genes recombination for the alpha chain, V, D, J, C genes recombination for the beta chain. The BM3.3 TCR variable domain is made of the following segments: TRAV16*01, TRAJ32 for the Valpha and Jalpha segments (chain A) TRBV1*01, TRBJ1-3*01 for the Vbeta, Jbeta segments (chain B). Author states the TCR variable domain is produced as a single chain Fv fragment. The Valpha domain (chain A) C-terminus is artificially connected to the Vbeta domain (chain B) N-terminus by the mean of a flexible hydrophilic linker (sequence GSADDASADDAKKDAAKKDDAKKDDAKKDGS) for wich no electron density is observed. Since this linker has no biological role and does not interfere with TCR recognition, it has not been incorporated in the model and the sequence record. |
