WebMar 1, 2024 · Although the KiH technology significantly improves heterodimer formation, hole-hole homodimerization can still occur at a low level (knob-knob homodimerization is rare as the two knobs will pose steric hindrance). WebIn a pioneering approach, Carter and colleagues from Genentech conceived the heterodimeric Fc variant and invented the so-called “Knobs-into-Holes (KiH)” Fc technology (21, 22). The concept was to introduce a “knob” in one CH3 domain (CH3A) by substitution of a small residue with a bulky one (i.e., T366W CH3A in EU numbering).
