HIST1H2BN
Histone H2B: A Critical Component of Chromatin Structure and Gene Regulation
Description:
Histone H2B is one of the four core histone proteins that form the building blocks of chromatin, the complex structure that packages DNA within eukaryotic cells. It consists of 120-123 amino acids and plays a crucial role in maintaining chromatin architecture, gene expression, and cellular processes.
Associated Diseases:
Mutations or abnormal modifications of histone H2B have been linked to several diseases, including:
- Cancer: Dysregulation of H2B can promote uncontrolled cell growth and tumorigenesis.
- Neurodegenerative disorders: Altered H2B expression or modifications have been found in Alzheimer's disease, Parkinson's disease, and Huntington's disease.
- Congenital abnormalities: Mutations in H2B can cause developmental disorders such as microcephaly and growth retardation.
Did you Know ?
H2B makes up approximately 25% of the total histone protein content in chromatin.
