1 Protein heterocomplex Heteromer Protein × 4 PDB declaration: tetrameric(4) Consistent with protein copy count Chain A; UniProt 62–265 Chain B; UniProt 62–265 Not recorded TERB1-TBM × 2 X-RAY DIFFRACTION X-ray crystallization conditions:VAPOR DIFFUSION, SITTING DROP;pH 8.5;289 K;TRF1-TRFH and TERB1-TBM were mixed in a 1:5 molar ratio and crystal screens set up using 0.3 microliter protein solution and 0.3 microliter reservoir solution in a sitting drop format. Diffracting crystals were obtained in 0.1 M Tris-Cl (pH 8.5) and 30% PEG 300. Crystals were cryoprotected in the crystallization solution plus 10% PEG 400 and harvested in liquid nitrogen. Resolution 2.10 Å R-free 0.210
