这个基因编码多囊蛋白家族的一个成员。编码的蛋白质包含11个跨膜结构域，即一个脂蛋白/ Cl 1-GPCR蛋白水解位点（GPS）结构域，和一个多囊蛋白-1，脂氧合酶，α毒素（PLAT）结构域。这种蛋白质可能是阳离子通道孔的组成部分这个基因在人类看来是一个多态性假基因，参考基因组编码一个非功能性等位基因。选择性剪接导致多个转录变体。

This gene encodes a member of the polycystin protein family. The encoded protein contains 11 transmembrane domains, a latrophilin/CL-1-like GPCR proteolytic site (GPS) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. This protein may function as a component of cation channel pores. This gene appears to be a polymorphic pseudogene in humans, and the reference genome encodes a non-functional allele. Alternative splicing results in multiple transcript variants.
