Extended Data Fig. 3: Position of RSS elements in traj genes of D. rerio.
From: Origin and evolutionary malleability of T cell receptor α diversity
a, Five major classes of J elements are present in the genome, distinguished by the distance between the RSS element (only heptamer sequence is shown) and the conserved Phe-Gly-X-Gly peptide tetrad. The distance from the FGXG to the splice donor site at the 3′-end of J elements is always identical. The numbering scheme follows Extended Data Fig. 2. b, Number of J elements in the genome, grouped relative to the position of RSS. c, Size distribution of expressed J elements, grouped relative to the position of RSS.
