Zebrafish (Danio rerio) TRA locus on chromosome 2

The zebrafish (Danio rerio) TRA locus is on chromosome 2. The orientation of the locus is forward (FWD).
The zebrafish (Danio rerio) TRA/TRD locus spans 540 kilobases (kb), from 10 kb upstream of the most 5' gene in the locus, TRDD1 (F), to 10 kb downstream of the most 3' gene in the locus, TRAV1-1 (F). The Locus representation encompasses 600 kb including the 3' borne DAD1.
The zebrafish (Danio rerio) TRA locus consists of 152 TRAV genes belonging to 75 TRAV subgroups,123 TRAJ segments and 1 TRAC gene [1].
The TRAV genes span 1774 kilobases (kb), the TRAJ genes span 61 kilobases (kb), the TRAC gene spans 16 kilobases (kb)

The CLUSTER includes 152 TRAV genes belonging to 75 subgroups (132 genes are functional, 7 genes are ORF and 13 genes are pseudogenes), 123 TRAJ (107 genes are functional, 15 genes are ORF and 1 gene is pseudogene) and 1 TRAC functional .
