Tag Info

N-terminal His-tagged/Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.

Buffer

Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0

Storage

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Shelf Life

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function(From Uniprot)

Histone H1 protein binds to linker DNA between nucleosomes forming the macromolecular structure known as the chromatin fiber. Histones H1 are necessary for the condensation of nucleosome chains into higher-order structured fibers. Acts also as a regulator of individual gene transcription through chromatin remodeling, nucleosome spacing and DNA methylation.

Gene References into Functions

Results show that histones H1.2 and H1.4 were observed in MDA-MB-231 metastatic breast cancer cells. The phosphorylation at S173 of histone H1.2 and S172, S187, T18, T146, and T154 of H1.4 significantly increases during M phase suggesting that these events are cell cycle-dependent. PMID:26209608
This study identified and confirmed HIST1H1E protein changes within the postsynaptic density in schizophrenia. PMID:25048004
the N-terminal domain of H1 is an important determinant of affinity and specificity of H1-chromatin interactions. PMID:22425985
PKA-mediated H1.4S35 phosphorylation dissociates H1.4 from mitotic chromatin but also suggest that this phosphorylation is necessary for specific mitotic functions. PMID:21852232
Allele-specific underacetylation of histone H4 downstream from promoter is associated with X-inactivation in human cells. PMID:12498347
the lysine residue adjacent to the phosphorylation site found on the serine residue on the H1.4 peptide KARKSAGAAKR was also shown to be methylated, raising the question of whether the hypothesized "methyl/phos" switch could be extended to linker histones PMID:15595731
