The HNK-1 epitope as a hallmark of many cell adhesion molecules is supposed to convey positive cellular interactions. Here, we report that in the adult chick the HNK-1 epitope is absent from active serum butyrylcholinesterases (BChE), but is strongly expressed on all inactive serum BChEs and on active brain BChE. These data further support roles of cholinesterases in cell adhesion, particularly so for their inactive forms. Moreover, we show that the HNK-1-positive BChEs belong to different types of glycoproteins.
作为许多细胞粘附分子标志的HNK-1表位被认为可传递积极的细胞间相互作用。在此,我们报告,在成年鸡中,活性血清丁酰胆碱酯酶(BChE)不存在HNK-1表位,但所有非活性血清BChE和活性脑BChE上均强烈表达该表位。这些数据进一步支持胆碱酯酶在细胞粘附中的作用,尤其是其非活性形式的作用。此外,我们表明HNK-1阳性BChE属于不同类型的糖蛋白。
