Anti-H1-7 Antibody Picoband®

H1 histone family, member N, testis-specific is a member of the histone family of nuclear proteins which are a component of chromatin. In humans, this protein is encoded by the H1FNT gene. Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4) . The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a replication-independent histone that is a member of the histone H1 family. The related mouse gene encodes a testis specific protein that is required for spermatogenesis and male fertility.

E.coli-derived human H1-7 recombinant protein (Position: H35-R130) . Human H1-7 shares 61.3% and 64.9 amino acid (aa) sequence identity with mouse and rat H1-7, respectively.
