Western blot analysis of NFYB over-expressed 293 cell line, cotransfected with NFYB Validated Chimera RNAi ( Cat # H00004801-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with NFYB monoclonal antibody (M01), clone 6H6 (Cat # H00004801-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
The protein encoded by this gene is one subunit of a trimeric complex, forming a highly conserved transcription factor that binds with high specificity to CCAAT motifs in the promoter regions in a variety of genes. This gene product, subunit B, forms a tight dimer with the C subunit, a prerequisite for subunit A association. The resulting trimer binds to DNA with high specificity and affinity. Subunits B and C each contain a histone-like motif. Observation of the histone nature of these subunits is supported by two types of evidence; protein sequence alignments and experiments with mutants. [provided by RefSeq
