Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The SA2 protein also known as stromal antigen 2 is a component of the cohesin complex playing a significant role in chromosomal dynamics. With an approximate molecular weight of 152 kDa SA2 exhibits high expression in the nucleus of proliferating cells particularly during interphase. This cohesin component contributes critically to maintaining sister chromatid cohesion and ensuring proper segregation during cell division serving as a functional partner in the cohesin complex with other components like SMC1 SMC3 and RAD21.
Biological function summary

SA2 plays an important role in regulating gene expression by forming loops that connect different genomic regions. SA2 as a member of the cohesin complex also participates in DNA repair by facilitating accurate recombination enhancing genome stability. This involvement is essential for maintaining chromatin structure which influences diverse cellular processes. Its expression can be an important modulator in the dynamic environment of cellular proliferation and differentiation.

Pathways

SA2 functions integrally within the cohesin-mediated sister chromatid cohesion pathway and the DNA damage response pathway. In these pathways SA2 teams with proteins such as CTCF in insulator function regulation and BRCA1 in DNA repair mechanisms. The cohesin-SA2 interaction with these proteins ensures proper chromosomal architecture and integrity which are essential for the accurate transmission of genetic material across generations of cells.

SA2 mutations or dysregulations have been linked to Cornelia de Lange Syndrome (CdLS) and certain cancers. In CdLS SA2 mutations disrupt normal cohesin function affecting developmental processes. In cancer contexts abnormal SA2 function or expression can lead to improper DNA repair contributing to genomic instability and tumorigenesis. It is often studied in concert with other cohesin proteins and regulatory elements like NIPBL which provides insights into cohesin-related pathologies and potential therapeutic targets.

Target data

Component of cohesin complex, a complex required for the cohesion of sister chromatids after DNA replication. The cohesin 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.
