这个基因编码的蛋白质是一种分子伴侣，它是包含tcp1复合物（cct）的伴侣蛋白的一个成员，也被称为tcp1环复合物（tric）。这个复合物由两个相同的堆叠环组成，每个环包含八种不同的蛋白质。未折叠的多肽进入复合物的中心腔，并以ATP依赖的方式折叠该复合物可折叠多种蛋白质，包括肌动蛋白和微管蛋白该基因突变导致遗传性感觉和自主神经病变伴痉挛性截瘫（HSNSP）选择性剪接导致多个转录变体相关假基因已在5号和13号染色体上鉴定。[由RefSeq提供，2015年4月]
The protein encoded by this gene is a molecular chaperone that is a member of the chaperonin containing TCP1 complex (CCT), also known as the TCP1 ring complex (TRiC). This complex consists of two identical stacked rings, each containing eight different proteins. Unfolded polypeptides enter the central cavity of the complex and are folded in an ATP-dependent manner. The complex folds various proteins, including actin and tubulin. Mutations in this gene cause hereditary sensory and autonomic neuropathy with spastic paraplegia (HSNSP). Alternative splicing results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 5 and 13. [provided by RefSeq, Apr 2015]
