抗体,也叫免疫球蛋白(Ig),是一种能特异性结合抗原的糖蛋白,而抗原是在易感染动物体内引发抗体产生的物质。在体内,抗体是由于外源性分子的侵袭而产生的。抗体以一个或者多个Y字形单体存在,每个Y字形单体由4条多肽链组成,包含两条相同的重链和两条相同的轻链。轻链和重链是根据它们的分子量大小来命名的。Y字形结构的顶端是可变区,为抗原结合部位。任何一个抗体的轻链都可以分为κ或λ型(基于小分子多肽结构上的差异),每一个抗体的重链则决定了它的类或型。
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
