Astrin also known as SPAG5 or Deepest is a protein important for cell division. It has a molecular mass of approximately 45 kDa. Researchers find Astrin primarily in the cytosol and preferably expressed in proliferating cells. Astrin plays a significant role in spindle stabilization during mitosis binding to microtubules to ensure proper chromosome segregation. This protein has become a focus of study due to its critical functions during cell cycle progression.
Biological function summary
Astrin facilitates kinetochore-microtubule attachment participating in the mitotic spindle assembly complex. This complex ensures chromosome alignment and segregation which is critical in cellular replication. Since precise regulation of this process is necessary for genetic stability Astrin's function is indispensable. Its presence influences the structural integrity of dividing cells linking it to the stability of genetic information passed to daughter cells after division.
Pathways
Astrin operates within the spindle assembly checkpoint and cell cycle pathways. The spindle assembly checkpoint pathway ensures that cells do not progress to anaphase until all chromosomes are properly attached to the spindle apparatus. In synergy with proteins like Ndc80 and KNL1 Astrin maintains attachment integrity. Its interactions with these proteins ensure accurate chromosome segregation protecting against chromosomal instability which can lead to aneuploidy.
Astrin's role connects it to conditions like cancer and developmental disorders. Overexpression of Astrin has associations with tumor progression since its function affects cell proliferation. In the context of cancer proteins like Aurora B also influence Astrin's activity. The misregulation of this pathway can lead to faulty chromosomal alignment and segregation contributing to oncogenesis. Such insights make Astrin a potential biomarker and therapeutic target in cancer research.
