The protein encoded by this gene belongs to the highly conserved cyclin family, whose members function as regulators of the cell cycle. This protein binds and activates cyclin-dependent kinase 2 and thus promotes transition through G1/S and G2/M. [provided by RefSeq, Aug 2016]
Forensic Context
A study in mice demonstrated that the CCNA2 was down-regulated in kidney tissue at 8 and 24 hours after whole-body irradiation with 10 Gy γ-rays, showing fold changes of 0.663 and 0.625, respectively [Zhao et al. DOI:10.1158/1078-0432.CCR-05-2418]. In human post-mortem tissues, the CCNA2 was down-regulated as part of the inhibited telomere maintenance pathway specifically in the lungs of patients who succumbed to septic shock [Pinheiro da Silva et al. DOI:10.1111/jcmm.17938]. A study in mice demonstrated that hyperoxia exposure significantly upregulated the CCNA2 mRNA level, suggesting a serious risk for developing fibrosing alveolitis [Shimada et al. DOI:10.1007/S00414-008-0226-6]. In human and mouse studies of heart failure post-myocardial infarction, the CCNA2 was identified as a hub gene in a specific fibroblast module [Wang et al. DOI:10.1016/j.ijbiomac.2025.143171].
