这个基因编码一种参与周围神经髓鞘维持的蛋白质。编码蛋白包含2个pdz结构域，分别以psd95（突触后密度蛋白）、dlga（果蝇椎间盘大肿瘤抑制蛋白）和zo1（哺乳动物紧密连接蛋白）命名。已经描述了该基因的两个选择性剪接转录变体，它们编码不同的蛋白质亚型，并且在雪旺细胞中具有不同的靶向性。该基因突变可引起腓骨肌萎缩症、4F型和Dejerine Sottas神经病变[由RefSeq提供，2008年7月]
This gene encodes a protein involved in peripheral nerve myelin upkeep. The encoded protein contains 2 PDZ domains which were named after PSD95 (post synaptic density protein), DlgA (Drosophila disc large tumor suppressor), and ZO1 (a mammalian tight junction protein). Two alternatively spliced transcript variants have been described for this gene which encode different protein isoforms and which are targeted differently in the Schwann cell. Mutations in this gene cause Charcot-Marie-Tooth neuoropathy, type 4F and Dejerine-Sottas neuropathy. [provided by RefSeq, Jul 2008]
