NCIt definition : Human HMGN1 wild-type allele is located in the vicinity of 21q22.2 and is approximately
7 kb in length. This allele, which encodes nonhistone chromosomal protein HMG-14 protein,
is involved in the modulation of chromatin modifications. The HMGN1 gene is overexpressed
in Down syndrome.;
NCIt note : The HMGN1 gene may play a role in the epigenetic regulation of gene expression. This
gene has also been proposed to be involved in chromatin remodeling during embryogenesis.
In mice, nonhistone chromosomal protein HMG-14 protein optimizes the cellular response
to ionizing radiation and to other tumorigenic events.;
