Comments [?]

Subcellular location Nucleus.
Domain The NBD (nonamer binding) DNA-binding domain mediates the specific binding to the nonamer RSS motif by forming a tightly interwoven homodimer that binds and synapses 2 nonamer elements, with each NBD making contact with both DNA molecules. Each RSS is composed of well-conserved heptamer (consensus 5'-CACAGTG-3') and nonamer (consensus 5'-ACAAAAACC-3') sequences separated by a spacer of either 12 bp or 23 bp.
Similarity Belongs to the RAG1 family.
