実施例1:免疫グロブリンFc領域におけるイオン相互作用を担うアミノ酸残基の同定
タンパク質3D構造解析ソフトウェアCn3D4.3.1を用いて、免疫グロブリン重鎖二量体の構造を分析した。PDBデータベースから、1L6X、1HZH、10QX、1H3X及び4HAGなどのIgGのX線結晶構造を詳細に調べた。2つの同様の重鎖間の密接な近接性のため、ヒンジ領域、N390〜S400のCH3ドメインエッジ界面、及びD401〜L410のCH3中間界面に特別に注目した。2つの同様の重鎖間の可能な相互作用アミノ酸残基対を以下に示す。

適切なイオン相互作用力を提供し、2つの異なる修飾された重鎖間のヘテロ二量体形成を促進するために、少なくとも2つ、好ましくは2つ〜6つ、最も好ましくは3つ〜4つの正電荷を帯びるアミノ酸(アルギニン又はリシンなど)を、連続的にまたは別々に第1重鎖における可能な相互作用アミノ酸位置に導入した。同時に、少なくとも2つ、好ましくは2つ〜6つ、最も好ましくは3つ〜4つの負電荷を帯びるアミノ酸(アスパラギン酸またはグルタミン酸など)を、連続的にまたは別々に前記した領域中の第2重鎖における可能な相互作用アミノ酸位置に導入した。突然変異を誘発するためのベクター構築物はInvivoGen(San Diego、CA)から購入した。pFUSE−CHIg−hG1は、ヒト伸長因子(elongation factor)1プロモーターに駆動されたCH1−ヒンジ−CH2−CH3断片の発現に用いられ、宿主細胞から発現産物を分泌させるように、通常の分子クローニングによってCHIのN末端の前にIL−2分泌シグナル配列を加えた。pFUSE−hIgG1−Fc2は、同じプロモーターによって駆動されたヒンジ−CH2−CH3断片の発現に用いられる。

ヘテロ二量体の形成の効果を評価するための実験方法を図2に示す。正電荷を帯びるアミノ酸の突然変異を導入したポリペプチド鎖A(通常は図中の長鎖である)、および負電荷を帯びるアミノ酸の突然変異を導入したポリペプチド鎖B(通常は図中の短鎖である)は、Life Technologiesの293fectinトランスフェクション試薬を用いて、単独でまたは共にHEK293細胞にトランスフェクトされた。HEK293細胞において、種々の正電荷および負電荷を帯びるポリペプチド鎖の組合せを共発現させた。本発明では、正電荷を帯びるポリペプチド鎖と負電荷を帯びるポリペプチド鎖との間の好ましい比率は1:1であるが、他の比率であっても良い。トランスフェクトされた3日後、遠心分離により細胞培養上清を採取し、プロテインA磁気ビーズ(Pierce)プルダウンを行った。磁気ビーズに結合したタンパク質産物は、SDS−PAGEゲル電気泳動におけるそれらの移動度に基づいて特徴を表す。結合したタンパク質を有する回収されたプロテインA磁性ビーズを、30μlのPBS緩衝液に再懸濁し、30μlのSDSローディングバッファーと混合して、5分間煮沸した。半量の煮沸したサンプルを10%SDS−PAGEにロードして、長鎖ホモ二量体、長鎖と短鎖ヘテロ二量体、および短鎖ホモ二量体を分離した。代表的なヘテロ二量体の形成の結果を図3、4、5、6および7に示す。
図8は、抗体の一段階精製の原理を示す。Fcを含むヘテロ二量体二重特異性または多重特異性抗体の精製は、当分野で公知の方法によって達成される。タンパク質精製プロセス後に高純度の二重特異性または多特異性抗体産物を得るために、一部の公知技術は、Fcヘテロ二量体における2つの鎖の1つにアミノ酸突然変異(例えば、H435R又はY436F)を意図的に導入して、プロテインAに対する結合活性を低下または除去することが提案されている。これらの方法は、US2014/0348839(Medlmmune)、WO2010/151792、US20140248664(Regeneron)、PEGS2015 GBR1302ポスター(Glenmark)に記載されている。ヘテロ二量体Fcにおけるこのような修飾は、Fcヘテロ二量体においてプロテインAに結合する鎖を1つのみ残させる。結果として、このようなヘテロ二量体は、野生型ホモ二量体と比較してプロテインAへの結合が弱いので、より高いpH(pH4.0〜5.0)で溶出することができる一方、通常のFcホモ二量体はpH2.8〜pH3.0でしか溶出できない。
