Description
ΔGbinding=ΔGcomplex−ΔGfree
結合エネルギー(Gbinding)は、標的タンパク質と非抗体タンパク質との結合に必要なエネルギーであって、標的タンパク質と非抗体タンパク質とが結合された状態でのエネルギー(Gcomplex)と結合前の標的タンパク質と非抗体タンパク質とのそれぞれのエネルギー(Gfree)の差で示すことができる。結合エネルギーが最も低い非抗体タンパク質から順次に整列する。
既に知られているヒトタンパク質をほとんど全部含むヒトタンパク質スキャフォールドのライブラリー製作のために、SCOP(Structural Classification of Proteins)データベースにあるヒトタンパク質のそれぞれが有する3次元的構造に応じて類型別に複数のグループで分類されているグループから5個の代表的な構造を選択した。組織浸透を容易にするために、分子量を限定して10−40kDaの分子量を有する代表タンパク質を5個以下で選択してすべての類型のヒトタンパク質を含むと共にライブラリーの規模を縮小した。そして、本発明者らは、PDBTM(Protein Data Bank of Transmembrane Proteins)データベースの注釈を用いて膜タンパク質の構造及びキーワード検索で抗体を除外させた。無差別的な結合を避けるために、10個以下の相互作用が知られているタンパク質のみを選択した。タンパク質の相互作用の数は、HPRD(Human Protein Reference Database)で計算した。また、SWISS−PROTデータベースの‘SUBNIT’セクションを基に同種四量体(homotetramer)、同種六量体(homohexamer)などのような同時に多い相互作用を有する同種多量体(homomultimer)を除いて、単量体(monomer)、同種二量体(homodimer)または同種三量体(homotrimer)を形成して作るタンパク質を選択した。
前記実施例1で製作したヒトタンパク質スキャフォールドライブラリーを基盤に、EGFRドメイン2に相補的な様子を有するスキャフォールドをスクリーニングするために、EGFRを有して大規模ドッキングシミュレーションによる仮想スクリーニングを行った(図1の(b))。その方法は、下記のようである。タンパク質ドッキングシミュレーションの本来目的は、現存するタンパク質−タンパク質相互作用を予測することであるが、本発明では二つのタンパク質の間の相補的な様子を見出し、新しいタンパク質−タンパク質相互作用を作るための目的として使用した。
EGFRドメイン2の結合に関与するスキャフォールドEGFRドッキング複合体から選択されたものなどの中で、最も安定した複合体形成エネルギーを有する少数の主導的なスキャフォールドを追加的な最適化のためにスクリーニングした(図1の(c))。
ΔGbinding=ΔGcomplex−ΔGfree
前記実施例3で選択したEGFR結合スキャフォールド(1OZJ)のDNA(配列番号6、図6)をGenscript(Piscataway,NJ)で合成し、結合領域の特定位置のランダム化のためにデザインしたNNKプライマーを(Genotech,Daejon,Korea)用いてランダム化した。ランダム化したスキャフォールドをSfiI(Roche,Indianapolis,IN)で切断してファージミドベクターpComb3Xにライゲイションし、electrocompetent ER2738(New England Biolabs,Beverly,MA)に形質転換させてランダムライブラリーを製作した。
<5−1>バイオパニング及びファージディスプレイ
EGFRに特異的な結合タンパク質を質的に向上させるために、親和度選択技術である5回のバイオパニングを下記のように行った。
本発明者らは、製造社の指示に応じてDynabead M-270 Epoxy(Dynal,Invitrogen,Carlsbad,CA)をコーティングしてブロッキングした。1.5μgEGFR(Sigma,St.Louis,MO)を1ml/mgになるようにPBS(137mM塩化ナトリウム、10mMリン酸塩、2.7mM塩化カリウム、ph7.4)をストック溶液(stock solution)で使用して5×106個のダイナビーズ(Dynabead)をパニングの各回ごとにコーティングした。EGFRにコーティングされたダイナビーズ(Dynabead)をランダム化したファージライブラリー500μlとともに2時間室温ローテータ(rotator)で培養した。結合しないファージを除去するために、ダイナビーズ(Dynabead)を0.05%Tween20を含むPBS(v/v)で一番目のバイオパニング後には1回、2及び3番目のバイオパニング後には3回、残った2回には、5回洗浄した。EGFR−コーティングされたダイナビーズ(Dynabead)に結合したファージを0.1Mグリシン−HCl(pH2.2)30μlを2回追加して溶離し、2MのTris−HCl(pH9.1)を追加して中性化させた。溶離されたファージを新鮮に成長させたER2738に感染させ、次のバイオパニングのために一晩培養した。
各コロニーをパニング最後の週期の算出量適定プレートでランダムに選択し、1mlのスーパーブロス(super broth)(3%トリプトン、2%酵母抽出、1%3−(N−モルホリノ)プロパンスルホン酸(3-[N-Morpholino]propanesulfonic acid)[MOPS]、pH7.0)に接種した。37℃で一晩培養の後に、培養上澄液をファージELISA(enzyme-linked immunosorbant assay)を行うのに使用した。微細適定プレートウェルを4℃で一晩の間4μg/mlEGFRを含むPBSでコーティングし、37℃で1時間3%BSAを含むPBSでブロッキングした。前記プレートをファージを含む培養上澄液とともに37℃で2時間培養し、0.05%Tween−20を含むPBS(PBST)で3回洗浄した。その後、ブロッキング緩衝溶液(1:2000)で希釈されたHRP(horseradish peroxidase)と結合した抗−M13抗体(Sigma)を加え、37℃で1時間培養した。50μlTMB基質溶液(Pierce、 Rockford,IL)を各ウェルに加え、650nmでODを測定した。
