TNR（tenascin R），癌症关联基因，基因ID：7143，该基因编码细胞外基质糖蛋白tenascin家族的一个成员。编码的蛋白质仅限于中枢神经系统。该蛋白可能在神经突起的生长、神经细胞的粘附和钠通道功能的调节中发挥作用它是围神经网的组成部分。[由RefSeq提供，2013年8月]This gene encodes a member of the tenascin family of extracellular matrix glycoproteins. The encoded protein is restricted to the central nervous system. The protein may play a role in neurite outgrowth， neural cell adhesion and modulation of sodium channel function. It is a constituent of perineuronal nets. [provided by RefSeq， Aug 2013]。
