抗體,也叫免疫球蛋白(Ig),是一種能特異性結合抗原的糖蛋白,而抗原是在易感染動物體內引發抗體產生的物質。在體內,抗體是由于外源性分子的侵襲而產生的。抗體以一個或者多個Y字形單體存在,每個Y字形單體由4條多肽鏈組成,包含兩條相同的重鏈和兩條相同的輕鏈。輕鏈和重鏈是根據它們的分子量大小來命名的。Y字形結構的頂端是可變區,為抗原結合部位。任何一個抗體的輕鏈都可以分為κ或λ型(基于小分子多肽結構上的差異),每一個抗體的重鏈則決定了它的類或型。
function:Suppresses Src-dependent tyrosine phosphorylation and activation of PDPK1 and its downstream signaling. Down-regulates PDPK1 kinase activity by interfering with tyrosine phosphorylation at the Tyr-9 Tyr-373 and Tyr-376 residues. May act as a tumor suppressor. Suppresses cell growth and enhanced sensitivity to various anticancer drugs.,similarity:Belongs to the NPR2 family.,subunit:Interacts with PDPK1.,tissue specificity:Most abundant in skeletal muscle, followed by brain, liver and pancreas, with lower amounts in lung, kidney, placenta and heart. Expressed in most lung cancer cell lines tested
