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??贵w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。

背景
This gene encodes a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes composed of a prodomain, a large protease subunit, and a small protease subunit. Activation of caspases requires proteolytic processing at conserved internal aspartic residues to generate a heterodimeric enzyme consisting of the large and small subunits. This protein is involved in the programmed cell death induced by Fas and various apoptotic stimuli. The N-terminal FADD-like death effector domain of this protein suggests that it may interact with Fas-interacting protein FADD. This protein was detected in the insoluble fraction of the affected brain region from Huntington disease patients but not in those from normal controls, which implicated the role in neurodegenerative diseases.
