CBF-A
The protein encoded by this gene is one subunit of a trimeric complex, forming a highly conserved transcription factor that binds to CCAAT motifs in the promoter regions in a variety of genes. Subunit A associates with a tight dimer composed of the B and C subunits, resulting in a trimer that binds to DNA with high specificity and affinity. The sequence specific interactions of the complex are made by the A subunit, suggesting a role as the regulatory subunit. In addition, there is evidence of post-transcriptional regulation in this gene product, either by protein degradation or control of translation. Further regulation is represented by alternative splicing in the glutamine-rich activation domain, with clear tissue-specific preferences for the two isoforms. [provided by RefSeq, Jul 2008]
Forensic Context
A study in mice demonstrated that in vivo α-particle irradiation of Kupffer and endothelial liver cells induced a characteristic inflammatory state, with Nuclear transcription factor-Y α (NFYA) specifically up-regulated following Kupffer cell-specific exposure [Roudkenar et al. DOI:10.1269/jrr.07078]. A separate review noted that NFYA is part of a unique transcriptional program in immature cardiocytes entering the cell cycle after myocardial infarction in mice, suggesting a role in proliferative function during cardiac repair [Li et al. DOI:10.3389/fcvm.2022.768834].
