Nuclear transcription factor Y subunit alpha is a protein that in humans is encoded by the NFYA gene. [5] [6]

Function

The protein encoded by this gene is one subunit of a trimeric complex NF-Y, forming a highly conserved transcription factor that binds to CCAAT motifs in the promoter regions in a variety of genes. [7] Subunit NFYA associates with a tight dimer composed of the NFYB and NFYC 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 NFYA 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. [8]

NF-Y complex serves as a pioneer factor by promoting chromatin accessibility to facilitate other co-localizing cell type-specific transcription factors. [9]

NF-Y has also been implicated as a central player in transcription start site (TSS) selection in animals. [10] It safeguards the integrity of the nucleosome-depleted region and PIC localization at protein-coding gene promoters.

Interactions

NFYA has been shown to interact with Serum response factor [11] and ZHX1. [11] [12] NFYA, NFYB and NFYC form the NFY complex and it has been shown that the NFY complex serves as a pioneer factor by promoting chromatin accessibility to facilitate other co-localizing cell type-specific transcription factors. [7]

Structure

The atomic structure of the NFY heterotrimer in complex with dsDNA was resolved via X-ray crystallography (PDB ID 4awl). [13] Using one of the NFYA alpha helices as a template, structure inspired stapled peptides were designed to disrupt the NFY heterotrimer formation by preventing NFYA from binding to the NFYB/C heterodimer. [14]

In molecular biology, a CCAAT box is a distinct pattern of nucleotides with GGCCAATCT consensus sequence that occur upstream by 60–100 bases to the initial transcription site. The CAAT box signals the binding site for the RNA transcription factor, and is typically accompanied by a conserved consensus sequence. It is an invariant DNA sequence at about minus 70 base pairs from the origin of transcription in many eukaryotic promoters. Genes that have this element seem to require it for the gene to be transcribed in sufficient quantities. It is frequently absent from genes that encode proteins used in virtually all cells. This box along with the GC box is known for binding general transcription factors. Both of these consensus sequences belong to the regulatory promoter. Full gene expression occurs when transcription activator proteins bind to each module within the regulatory promoter. Protein specific binding is required for the CCAAT box activation. These proteins are known as CCAAT box binding proteins/CCAAT box binding factors.
