Storage

Store at -20°C, for extended storage, conserve at -20°C or -80°C.

Shelf Life

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.

Notes

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

Target Background

Function

Histone acetyltransferase that plays a role in different biological processes including cell cycle progression, glucose metabolism, histone production or DNA damage repair. Coordinates histone production and acetylation via H4 promoter binding. Acetylates histone H4 at 'Lys-5' (H4K5ac) and 'Lys-12' (H4K12ac) and, to a lesser extent, histone H2A at 'Lys-5' (H2AK5ac). Drives H4 production by chromatin binding to support chromatin replication and acetylation. Since transcription of H4 genes is tightly coupled to S-phase, plays an important role in S-phase entry and progression. Promotes homologous recombination in DNA repair by facilitating histone turnover and incorporation of acetylated H3.3 at sites of double-strand breaks. In addition, acetylates other substrates such as chromatin-related proteins. Acetylates also RSAD2 which mediates the interaction of ubiquitin ligase UBE4A with RSAD2 leading to RSAD2 ubiquitination and subsequent degradation.; (Microbial infection) Contributes to hepatitis B virus (HBV) replication by acetylating histone H4 at the sites of 'Lys-5' and 'Lys-12' on the covalently closed circular DNA (cccDNA) minichromosome leading to its accumulation within the host cell.

The expression of HAT1 and MYST1, did not differ between drug-sensitive and -resistant cells PMID:18458078
Human histone acetyltransferase 1 (Hat1) acetylates lysine 5 of histone H2A in vivo. PMID:24682716
The high-resolution crystal structure of a Hat1p/Hat2p/CoA/H4 peptide complex was solved and it was found that the H4 tail interacts with both Hat1p and Hat2p, by which substrate recruitment is facilitated. It was discovered that H3 N-terminal peptides can bind to the Hat2p WD40 domain. PMID:24835250
Signalling from Toll-like or TNF-alpha receptors triggers the calcium/calmodulin-dependent protein kinase (CaMK2) to activate histone acetyltransferase-1 (HAT1), which then acetylates the transcriptional regulator PLZF. Acetylation of PLZF promotes the assembly of a repressor complex incorporating HDAC3 and the NF-kappa B p50 subunit that limits the NF-kappa B response. PMID:25865065
HAT1 is involved in the STAT5 binding to the Bcl2L12 promoter. HAT1 increased the expression of Bcl2L12. Bcl2L12 mediated the effects of HAT1 on suppressing NPC cell apoptosis. Absorption of the HAT1 shRNA plasmid-carrying liposomes induced NPC cell apoptosis. In conclusion, inhibition of HAT1 can induce NPC cell apoptosis via increasing Bcl2L12 expression, which can be a potential therapy for NPC treatment. PMID:29621521
HAT1 was upregulated in hepatocellular carcinoma.HAT1 acts as an oncogenic protein promoting cell proliferation and inducing cisplatin resistance in hepatocellular carcinoma. PMID:27938492
Nuclear HDAC2 immunopositivity was significantly higher in actinic cheilitis (AC) when compared with lip squamous cell carcinoma (LSCC). HDAC1 and HAT1 nuclear immunostaining were higher in AC, with no statistical significance. When comparing data with our previous study, we found a positive correlation between HDAC1 X DNMT1/DNMT3b, HDAC2 X DNMT3b, and HAT1 X DNMT1/DNMT3b for certain studied groups. PMID:28107582
AMPK phosphorylates DNMT1, RBBP7, and HAT1 and increases interactions of DNMT1, RBBP7, and HAT1. PMID:28143904
Results show a novel interaction of the Lsm4 RGG domain with HAT1 and RBBP7, leading to the possibility of a posttranslational modifications network involved in mRNP regulation. PMID:27247266
These data indicated that miR-486 aggravate the cholesterol accumulation in THP-1 cells by targeting HAT1. PMID:26654953
The expression of HAT1 was higher in the primary Esophageal carcinoma tumors and adjacent tissue as compared to that of the normal esophageal tissue and HAT1 expression was directly correlated with the poor tumor differentiation PMID:25120766
Data indicate that HAT1 is required for homologous recombination in DNA repair. PMID:23653357
the role of Hat1 in DNA damage repair is evolutionarily conserved, the ability of H3 acetylation to compensate for Hat1 deletion appears to be more variable PMID:17052979
HAT gene expression is required for cisplatin resistance and Clock and Tip60 regulate not only transcription, but also DNA repair, through periodic histone acetylation PMID:18458078
