产品介绍:该基因是 SCC3 家族的成员,在细胞核中表达。 它编码黏附素的一个成分,这是一种多亚基蛋白质复合物,它在从 DNA 复制到前期和前期的染色体长度上提供姐妹染色单体的凝聚力,之后它被解离,为后期分离做准备。
Function: Component of cohesin complex, a complex required for the cohesion of sister chromatids after DNA replication. The cohesion complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis.
Subunit: Interacts directly with RAD21 in cohesin complex. Cohesin complexes are composed of a heterodimer between a SMC1 protein (SMC1A or SMC1B) and SMC3, which are attached via their hinge domain, and RAD21 which link them at their heads, and one STAG protein (STAG1, STAG2 or STAG3). In cohesin complexes, STAG1 is mutually exclusive with STAG2 and STAG3.
