描述：

CD56 (NCAM) (123C3)小鼠单抗检测内源性总的CD56蛋白。单抗由小细胞肺癌标本制备的膜免疫BALB/c小鼠产生。NCAM(神经细胞粘附分子, CD56)是一个粘附糖蛋白，带有五个胞外免疫球蛋白样结构域，跟着两个纤连蛋白III型重复单元。结构多样性是通过选择性剪接导致不同的胞质结构域造成（1）。NCAM通过homo和异染性的相互作用调节神经附着，轴突延伸和细胞间相互作用。PSA(多唾液酸)翻译后修饰NCAM并增加小细胞肺癌转移潜能，Wilms+肿瘤，神经细胞瘤和横纹肌肉瘤（2）。CD56和CD16普遍用于确定NK细胞了，虽然一些带有T细胞标志物CD3和CD4的细胞液表达CD56（3）。

Background

NCAM (neural cell adhesion molecule, CD56) is an adhesion glycoprotein with five extracellular immunoglobulin-like domains followed by two fibronectin type III repeats. Structural diversity is introduced by alternative splicing resulting in different cytoplasmic domains (1). NCAM mediates neuronal attachment, neurite extension and cell-cell interactions through homo and heterophilic interactions. PSA (polysialic acid) post-translationally modifies NCAM and increases the metastatic potential of small cell lung carcinoma, Wilms+ tumor, neuroblastoma and rhabdomyosarcoma (2). CD56 and CD16 are commonly used to identify NK cells although some cells with the T cell markers CD3 and CD4 also express CD56 (3).
