这个基因编码一个大的细胞质动力蛋白，它参与纤毛的逆行运输，并在鞭毛内运输中发挥作用，这是纤毛/鞭毛组装所必需的过程。该基因的突变引起与原发性纤毛功能改变有关的异质性疾病谱，常涉及多指畸形、骨骼发生和多囊肾。选择性剪接导致编码不同蛋白质的多个转录变体。

This gene encodes a large cytoplasmic dynein protein that is involved in retrograde transport in the cilium and has a role in intraflagellar transport, a process required for ciliary/flagellar assembly. Mutations in this gene cause a heterogeneous spectrum of conditions related to altered primary cilium function and often involve polydactyly, abnormal skeletogenesis, and polycystic kidneys. Alternative splicing results in multiple transcript variants encoding distinct proteins.
