该基因编码brca1-brca2复合物（brcc）的一个亚单位，它是一种e3泛素连接酶。这种复合物在dna损伤反应中起作用，它负责brca1在dna断裂位点的稳定积累。该基因编码的组分能特异性地切割Lys 63连锁的多泛素链，并调节染色质中这些多泛素链的丰度该基因的缺失导致血管生成异常，并与脑血管病综合征-烟雾病有关。选择性剪接导致多个转录变体在5号染色体上发现了一个相关的假基因。[由RefSeq提供，2011年6月]
This gene encodes a subunit of the BRCA1-BRCA2-containing complex (BRCC), which is an E3 ubiquitin ligase. This complex plays a role in the DNA damage response, where it is responsible for the stable accumulation of BRCA1 at DNA break sites. The component encoded by this gene can specifically cleave Lys 63-linked polyubiquitin chains, and it regulates the abundance of these polyubiquitin chains in chromatin. The loss of this gene results in abnormal angiogenesis and is associated with syndromic moyamoya, a cerebrovascular angiopathy. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 5. [provided by RefSeq, Jun 2011]
