SA1 also known as Stromal Antigen 1 or cohesin subunit SA-1 plays a role in chromosome segregation and sister chromatid cohesion. It has a molecular weight of approximately 130 kDa. SA1 shows expression in various tissues with notable levels in the nucleus of dividing cells. The protein functions as a part of the cohesin complex contributing to its role in regulating the structure and function of chromosomes.
Biological function summary
SA1 works within the cohesin complex alongside other subunits such as SMC1 SMC3 and Rad21. This complex maintains sister chromatid cohesion ensuring proper chromosome alignment and separation during mitosis and meiosis. SA1's interaction within the cohesin complex helps modulate its ability to regulate transcription DNA repair and chromosome organization.
Pathways
SA1 participates in the cohesin pathway which is essential for cell cycle regulation and genomic stability. SA1 interacts with other proteins such as CTCF to facilitate chromosomal loop formation influencing gene expression. Additionally it operates within the DNA damage response pathway aiding in the repair processes by coordinating cohesin-dependent repair mechanisms and maintaining genomic stability.
SA1 has implications in Cornelia de Lange Syndrome (CdLS) and certain cancers. Mutations or dysregulation of SA1 can lead to CdLS a developmental disorder characterized by growth abnormalities and cognitive challenges where Rad21 also plays a role. Moreover altered SA1 expression or function associates with tumorigenesis as its role in chromosome segregation and stability is critical in avoiding aneuploidy and chromosomal instability typical in cancer progression.
