In molecular biology, a CCAAT box (also sometimes abbreviated a CAAT box or CAT box) is a distinct pattern of nucleotides with GGCCAATCT consensus sequence that occur upstream by 60-100 bases to the initial transcription site. (B) A relatively large nf-ya1-1 nodule has a small nodule meristem ( infection threads are indicated by arrows).(2014). The CCAAT box-binding transcription factor NF-YA1 controls rhizobial infection. Two CCAATboxbinding transcription factors redundantly regulate early steps of the legumerhizobia endosymbiosis.In this study, we bring convincing evidence that the Medicago truncatula CCAATboxbinding NFYA1 TF, previously associated with later stages of rhizobial We further demonstrated that the basal expression of these CCAAT box-containing proteasome genes is regulated by the transcription factor NF-Y. Knockdown of NF-YA, an essential subunit of NF-Y, reduced proteasome gene expression and compromised the cellular proteasome activity. NF-Y is a CCAAT-specific transcription factor thought to be involved in the regulation of a variety of eukaryotic genes.Diverse DNA binding proteins have been reported to bind to CCAAT boxes, either with exquisite specificity or with a loose specificity encompassing the CCAAT motif (for refs The CCAAT box-binding transcription factor NF-YA1 controls rhizobial infection.

The sequence-specific transcription factor NF-Y binds the CCAAT box, one of the sequence elements most frequently found in eukaryotic promoters. NF-Y is composed of the NF-YA and NF-YB/NF-YC subunits, the latter two hosting histone-fold domains (HFDs). MtNF-YA1 is a Medicago truncatula CCAAT box-binding transcription factor (TF), formerly called HAP2-1, highly expressed in mature nodules and required for nodule meristem functionIt is proposed that MtNF-YA1 controls rhizobial infection progression by regulating the formation and the wall of ITs. CBF, NF1, C/EBP Sp1. CCAAT GGGCGG.The GC box is a binding site for the transcription factor Sp1. Sp1 was initially identied as one of three components required for the transcription of SV40 early and late promoters. The CCAAT box-binding transcription factor NF-YA1 controls rhizobial infection. Bookmark.Reevaluating the infection status by the Wolbachia endosymbiont in Drosophila Neotropical species from the willistoni subgroup. NF-YA1, NF-YA2, and CRE1 (Soyano et al 2013 Verni et al 2015) was slightly repressed, suggesting that the regulation.(2014). Two CCAAT-box-binding transcription factors redundantly regulate early steps of the legume-rhizobia endosymbiosis. NF-Y transcription factor binds to CCAAT boxes on promoters of cell cycle regulatory genes such as cdc2, cyclin B, cdc25C, and cyclin A. We previously reported that the DNA binding activity of NF-Y is regulated by p53-p21-cdk2 pathway. The CCAAT box-binding transcription factor NF-YA1 controls rhizobial infection.

By chromatin immunoprecipitation experiments, we demonstrate herein that NF-Y does not bind to the CCAAT boxes of target promoters in differentiated muscle cells.Transcription Factors. NF-Y transcription factors consist of three unique proteins, called NF-YA, NF-YB, and NF-YC, and40. Laloum T, De Mita S, Gamas P, Baudin M, Niebel A. CCAAT-box binding transcription factors in plants: YA C subunit of the plant nuclear factor NF-Y required for rhizobial infection and nodule NF-Y is composed of the NF-YA and NF-YB/NF-YC subunits, the latter two hosting histone-fold domains (HFDs The sequence-specific transcription factor NF-Y binds the CCAAT box, one of the sequence elements most frequently found in eukaryotic promoters.

MOTIVATION: Identifying transcription factor binding sites is the first step in pinpointing non-coding mutations that disrupt the regulatory function of transcription factors and promote disease. ChIP-seq is the most common method for identifying binding sites The binding of transcription factor proteins (TFs) to DNA promoter regions upstream of gene transcription start sites (TSSs) is one of the most important mechanisms by which gene expression, and thus many cellular processes, are controlled. Rsum: Transcription factors belonging to the CCAAT-box binding factor family (also known as the Nuclear Factor Y) are present in all higher eukaryotes.In this review, we focus on recent findings concerning the expression patterns and potential functions of different members of these NF-Y protein NF-Y binds a CCAAT motif found in many eukaryotic polymerase II-dependent promoters.Interaction between NF-Y and X box binding proteins was demonstrated by reciprocal co-immunoprecipitation in the 1 The abbreviations used are: FPB, Foot Printing B EMSA, electrophoretic mobility shift assay C/EBP, CCAAT/enhancer binding protein CBF, CCAAT binding factor wt, wild type CTF, CCAAT transcription factor NF-Y, nuclear factor for Y box.

In this study, we bring strong evidence that the Medicago truncatula CCAAT box-binding NF-YA1 TF, previously associated with later stages of rhizobial infection and nodule meristem formation is, together with its closest homolog NF-YA2 The nucleotide sequences of potential binding sites for the transcription factors Sp1, Sp3, CCAAT binding factor (CBF), and nuclear factor 1 (NF-1) present in the human COL1A1 promoter region from 2174 to 250 bp are depicted in open boxes. Nuclear factor Y (NF-Y) is a heterotrimeric transcription factor (TF) complex which binds specifically to the CCAAT-box cis-element in eukaryotes. The three NF-Y subunits, NF-YA (HAP2/CBF-B), NF-YB (HAP3/CBF-A) and NF-YC (HAP5/CBF-C) Since changes in gene expression are extensive and global during ageing, involvement of general transcription regulators in the phenomenon is likely.
