该基因编码的蛋白属于plakin蛋白家族，在细胞骨架结构的组织中起着重要作用这个家族成员由几个高度同源的plakin重复序列组成它可能维持上皮细胞角蛋白中间丝网络的完整性对小鼠原代蛋白的研究表明，它在伤口愈合过程中加速了角质形成细胞的迁移[由RefSeq提供，2013年10月]
The protein encoded by this gene belongs to the plakin family of proteins, which play a role in the organization of cytoskeletal architecture. This family member is composed of several highly homologous plakin repeats. It may function to maintain the integrity of keratin intermediate filament networks in epithelial cells. Studies of the orthologous mouse protein suggest that it accelerates keratinocyte migration during wound healing. [provided by RefSeq, Oct 2013]
