CUL3

这个基因编码一个库林蛋白家族的成员。编码蛋白作为e3泛素连接酶复合物的核心组分和支架蛋白，在多泛素化和随后的降解过程中起着关键作用。包括编码蛋白在内的复合物也可能在内胚体的晚期成熟中起作用。该基因突变是2e型假醛固酮减少症的一个原因。另外，已经观察到该基因编码多个亚型的剪接转录变体。[由RefSeq提供，2012年3月]
This gene encodes a member of the cullin protein family. The encoded protein plays a critical role in the polyubiquitination and subsequent degradation of specific protein substrates as the core component and scaffold protein of an E3 ubiquitin ligase complex. Complexes including the encoded protein may also play a role in late endosome maturation. Mutations in this gene are a cause of type 2E pseudohypoaldosteronism. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Mar 2012]
