  • Function
    Involved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-
    -Gly-217' bond. Cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop-helix leucine zipper domain and the membrane attachment domain. Cleaves and activates caspase-6, -7 and -9. Involved in the cleavage of huntingtin.
  • Tissue specificity
    Highly expressed in lung, spleen, heart, liver and kidney. Moderate levels in brain and skeletal muscle, and low in testis. Also found in many cell lines, highest expression in cells of the immune system.
  • Sequence similarities
    Belongs to the peptidase C14A family.
  • Post-translational
    Cleavage by granzyme B, caspase-6, caspase-8 and caspase-10 generates the two active subunits. Additional processing of the propeptides is likely due to the autocatalytic activity of the activated protease. Active heterodimers between the small subunit of caspase-7 protease and the large subunit of caspase-3 also occur and vice versa.
    S-nitrosylated on its catalytic site cysteine in unstimulated human cell lines and denitrosylated upon activation of the Fas apoptotic pathway, associated with an increase in intracellular caspase activity. Fas therefore activates caspase-3 not only by inducing the cleavage of the caspase zymogen to its active subunits, but also by stimulating the denitrosylation of its active site thiol.

  • ab2171 staining human tonsil by IHC-P.

  • Immunohistochemistry (Frozen sections) analysis of rabbit cornea tissue (on day 4, 10 and 15 after the injury) labelling Caspase-3 with ab2171. E − corneal epithelium. a – Caspase-3 staining is strong in the epithelium (particularly in superficial layers, arrows) of injured corneas on day 4 (a) as well as 10 (b) after the injury (arrows). c – On day 15 after the injury the expression of caspase-3 is present in the corneal epithelium as well as in the corneal stroma (arrows show to the cell apoptosis). The sections are counterstained with haematoxylin. Scale bar: 10 μM.

  • Immunohistochemistry (Frozen sections) analysis of rabbit cornea tissue (on day 4, 10 and 15 after the injury treated with MSCs) labelling Caspase-3 with ab2171. E − corneal epithelium. d – The expression of caspase-3 is reduced in the epithelium (arrows) of injured corneas treated with MSCs on nanofiber scaffolds from day 4 (d), day 10 (e) as well as day 15 (f) after the injury. Solely apoptosis (arrows) are seen. The sections are counterstained with haematoxylin.

  • Immunohistochemistry (Frozen sections) analysis of rabbit cornea tissue labelling Caspase-3 with ab2171. g - Caspase-3 expression is absent in a control cornea. h – The primary antibody is omitted from the incubation medium. The section is stained by counterstaining only (as a negative control for caspase-3). E − corneal epithelium.
