Justification for analogy
From the 1htj paper, the last three helices (helix 10-12) are an integral extension of the RGS fold with many hydrophobic interactions. The last three helices are absent in other RGS, so they are insertions. The 3-helix motif in 1htj is a hybrid, using 1 helix from the insertion and 2 helices from the RGS core.

In the alignments below, two upper-case letters are aligned, while two lower-case letters are NOT aligned. The two sequences in an alignment are NOT continuous in most cases (see their ranges). The superpositions are re-constructed from the corresponding alignments by minimizing the overall RMSD. In a PDB-format superposition file, the first domain is represented by chain S and the second domain is represented by chain A.
