Dog (Canis lupus familiaris) TRA locus on chromosome 8

The dog (Canis lupus familiaris) TRA locus is on chromosome 8. The orientation of the locus is forward (FWD).
The dog (Canis lupus familiaris) TRA/TRD locus spans 762 kilobases (kb), from 10 kb upstream of the most 5' gene in the locus, TRAV43-1 (F), to 10 kb downstream of the most 3' gene in the locus, TRAC (F). The Locus representation encompasses 800 kb including the 3' borne DAD1.
The dog (Canis lupus familiaris) TRA locus consists of 58 TRAV genes belonging to 32 TRAV subgroups, 59 TRAJ segments and 1 TRAC gene [1].
The TRAV genes span 544 kilobases (kb), the TRAJ genes span 74 kilobases (kb), the TRAC gene spans 6 kilobases (kb)

The CLUSTER includes 58 TRAV genes belonging to 32 subgroups (34 genes are functional, 1 is ORF and 23 genes are pseudogenes), 59 TRAJ (40 genes are functional, 12 genes are ORF and 7 genes are pseudogenes) and 1 TRAC functional .
