Protein

Non-histone chromosomal protein 6B

Gene

NHP6B

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

DNA-binding protein that induces severe bending of DNA. Required for DNA-binding by the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. Also augments the fidelity of transcription by RNA polymerase III independently of any role in the FACT complex. Required for transcriptional initiation fidelity of some but not all tRNA genes. Seems to be functionally redundant with NHP6A.9 Publications

Interactioni

Subunit structurei

Weakly associates with the stable SPT16-POB3 heterodimer to form the FACT (yFACT or SNP) complex, which is associated with nucleosomes. Multiple molecules of NHP6 (NHP6A and/or NHP6B) are required to recruit the SPT16-POB3 heterodimer to DNA.
