该基因编码的蛋白质是果蝇黑胃管Capicua基因的一个同源基因,是转录抑制因子的高迁移率群(HMG)盒超家族成员。该蛋白包含一个参与DNA结合和核定位的保守HMG结构域和一个保守的C端。研究表明,这种蛋白的N末端区域与ATXN1(geneid:6310)相互作用,形成转录抑制复合物,体外研究表明,ATXN1的聚谷氨酰胺扩张可能改变这种复合物的抑制活性。该基因突变与少突胶质瘤有关(pmid:21817013)。此外,导致dux4(geneid:100288687)和fox4(geneid:4303)基因融合的易位事件与圆细胞肉瘤有关。在染色体1、4、6、7、16、20和Y染色体上发现了该基因的多个假基因。选择性剪接导致编码不同亚型的多个转录变体。
The protein encoded by this gene is an ortholog of the Drosophila melanogaster capicua gene, and is a member of the high mobility group (HMG)-box superfamily of transcriptional repressors. This protein contains a conserved HMG domain that is involved in DNA binding and nuclear localization, and a conserved C-terminus. Studies suggest that the N-terminal region of this protein interacts with Atxn1 (GeneID:6310), to form a transcription repressor complex, and in vitro studies suggest that polyglutamine-expansion of ATXN1 may alter the repressor activity of this complex. Mutations in this gene have been associated with olidogdendrogliomas (PMID:21817013). In addition, translocation events resulting in gene fusions of this gene with both DUX4 (GeneID:100288687) and FOXO4 (GeneID:4303) have been associated with round cell sarcomas. There are multiple pseudogenes of this gene found on chromosomes 1, 4, 6, 7, 16, 20, and the Y chromosome. Alternative splicing results in multiple transcript variants encoding different isoforms.
