NCAM1（neural cell adhesion molecule 1），癌症关联基因，基因ID：4684，这个基因编码一种细胞粘附蛋白，它是免疫球蛋白超家族的成员。编码蛋白在发育和分化过程中参与细胞与细胞的相互作用以及细胞与基质的相互作用编码蛋白已被证实参与神经系统的发育，参与T细胞和树突状细胞扩张的细胞在免疫监视中发挥重要作用选择性剪接导致多个转录变体[由RefSeq提供，2011年6月]This gene encodes a cell adhesion protein which is a member of the immunoglobulin superfamily. The encoded protein is involved in cell-to-cell interactions as well as cell-matrix interactions during development and differentiation. The encoded protein has been shown to be involved in development of the nervous system， and for cells involved in the expansion of T cells and dendritic cells which play an important role in immune surveillance. Alternative splicing results in multiple transcript variants. [provided by RefSeq， Jun 2011]。
