表達區(qū)間及表達系統(tǒng)(Source)
Human IGF-I R, His Tag (IGR-H5229) is expressed from human 293 cells (HEK293). It contains AA Glu 31 - Asn 932 (Accession # P08069-1).
Predicted N-terminus: Glu 31
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus.
This protein contains a furin convertase cleavage site, 737-RKRR-740, and will be partially processed into N (α chain) and C-terminal fragment (partial β chain) with calculated MW of 81.0 kDa and 23.8 kDa respectively. The protein migrates as 35-45 kDa (partial β chain), 110-120 kDa (α chain) and 130 kDa (α chain & partial β chain) under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
胰島素樣生長因子1受體(IGF1R)也稱為CD221、JTK13。并且是被IGF-1和相關(guān)生長因子IGF-2激活的跨膜受體。它屬于一大類酪氨酸激酶受體。該受體介導IGF-1的作用,IGF-1是一種分子結(jié)構(gòu)與胰島素相似的多肽蛋白激素。IGF1R由兩個α亞基和兩個β亞基組成,α和β亞基都是由單個信使核糖核酸前體合成的。然后將前體糖基化,蛋白水解裂解,并通過半胱氨酸鍵交聯(lián),形成功能性跨膜αβ鏈。α鏈位于細胞外,而β亞基橫跨細胞膜,負責配體刺激下的細胞內(nèi)信號轉(zhuǎn)導。IGF1R具有ATP的結(jié)合位點,ATP用于提供用于自身磷酸化的磷酸鹽。IGF1R和胰島素受體之間有60%的同源性。作為對配體結(jié)合的反應(yīng),α鏈誘導β鏈的酪氨酸自磷酸化。這一事件觸發(fā)了細胞內(nèi)信號的級聯(lián),雖然有一定的細胞類型特異性,但通常促進細胞存活和細胞增殖。
