  • 機能
    Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.
  • 関連疾患
    Defects in ACTA2 are the cause of aortic aneurysm familial thoracic type 6 (AAT6) [MIM:611788]. AATs are characterized by permanent dilation of the thoracic aorta usually due to degenerative changes in the aortic wall. They are primarily associated with a characteristic histologic appearance known as 'medial necrosis' or 'Erdheim cystic medial necrosis' in which there is degeneration and fragmentation of elastic fibers, loss of smooth muscle cells, and an accumulation of basophilic ground substance.

レビューと Q&A

I can confirm that these three antibodies recognize the mouse protein and the host species in which they were raised is also mouse. This may cause some non-specificity signal problem mainly in immunohistochemical using tissue sections (mouse-on-mouse) ...
