IgStrand: A universal residue numbering scheme for the immunoglobulin-fold (Ig-fold) to study Ig-proteomes and Ig-interactomes
Fig 9
Example of the Ig-extended Lamin Tail Domain (LTD).
A) Schematic LTD strand topology forming sheets ABED+ and A-GFCC’. B) Pseudo symmetric LTD dimer brings the two A-GFCC’ as one in antiparallel through the additional A- strand at the N terminus. C) LTD dimerization interface using the IgStrand numbers for the A- strand (i=1; j=4 running from 1445 to 1452) and a few residues on strand A and B. Note that the current IgStrand numbering does not cover residues before 1445 (based on current template - see Table 1) https://structure.ncbi.nlm.nih.gov/icn3d/share.html?BRks581vEqzUpENs9&t=7DTG.
