Function
Caspase 3 is a central executioner caspase in apoptosis, where initiator caspase 9 activates executioner caspases 3 and 7 by proteolysis[1]. Mechanistically, caspase 3 cleaves caspase 9 at Asp330 and enhances apoptosis by relieving XIAP-mediated inhibition, rather than directly activating caspase 9[1]. This places caspase 3 within apoptosome-linked feedback control and inhibitor-of-apoptosis regulation, while preserving a distinct functional profile from caspase 7[1][2]. Compared with caspase 7, caspase 3 can cleave caspase 9 under physiologically relevant conditions, and engineered activation studies show that caspase 3 or caspase 7, but not caspase 6 alone, is sufficient to induce apoptosis[1][2]. In disease models, caspase 3 and caspase 7 deletion did not reduce infarct size or ventricular remodeling after transient myocardial ischemia-reperfusion, limiting assumptions about canonical caspase-dependent apoptosis in adult cardiomyocytes[3]. In prostate cancer samples, procaspase 3 and cleaved caspase 3 predicted biochemical progression after radical prostatectomy, supporting their use as apoptosis-related tumor markers[4]. For experimental applications, caspase 3 research benefits from isoform-aware probes because common DEVD-based peptide inhibitors and substrates cannot reliably distinguish caspase 3 from caspase 7[5].

Expression
Tissue_specificity:It is highly expressed in the lungs, spleen, heart, liver, and kidneys. It is moderately expressed in the brain and skeletal muscle, and lowly expressed in the testes. It is also present in many cell lines, with the highest expression in immune system cells. -
Subunit
Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 17 kDa (p17) and a 12 kDa (p12) subunit. Interacts with BIRC6/bruce
