產(chǎn)品提供形式：

Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質(zhì)期：

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.
貨期：

Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
注意事項：

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

靶點詳情

功能：

Histone chaperone that facilitates histone deposition and histone exchange and removal during nucleosome assembly and disassembly. Cooperates with chromatin assembly factor 1 (CAF-1) to promote replication-dependent chromatin assembly and with HIRA to promote replication-independent chromatin assembly. Required for the formation of senescence-associated heterochromatin foci (SAHF) and efficient senescence-associated cell cycle exit.

1. ASF1A is aberrantly over-expressed in GIC tumors and plays key roles in GIC development and progression by stimulating the transcription of beta-catenin target genes. PMID: 28625518
2. ASF1a promotes non-homologous end joining repair by facilitating phosphorylation of MDC1 by ATM at double-strand breaks. PMID: 28943310
3. Data show that the ubiquitin-conjugating enzyme E2 RAD6A/B-MDM2 ubiquitin ligase machinery regulates anti-silencing function 1A protein (ASF1A) degradation. PMID: 26336826
4. quaternary complex of histone H3-H4 heterodimer with chaperone ASF1 and the replicative helicase subunit MCM2 PMID: 26186914
5. Thermodynamic analysis of the quaternary complex together with structural modeling support that ASF1 and MCM2 could form a chaperoning module for histones H3 and H4 protecting them from promiscuous interactions. PMID: 25618846
6. Data indicate Tousled-like kinases (TLK1) phosphorylation has an impact on cell cycle proteins Asf1a and Asf1b function. PMID: 24598821
7. findings show that ASF1A, a histone-remodeling chaperone specifically enriched in the metaphase II oocyte, is necessary for reprogramming of adult dermal fibroblasts into undifferentiated induced pluripotent stem cell PMID: 25035411
8. The ATR checkpoint pathway causes a histone chaperone normally associated with the replication fork, ASF1a, to degrade through a CRL1(betaTRCP)-dependent ubiquitination/proteasome pathway, leading to the localized dechromatinization and gene repression. PMID: 24700029
9. Co-depletion of the histone chaperones ASF1a and ASF1b in human cells induces all hallmarks of alternative lengthening of telomeres in both primary and cancer cells. PMID: 24413054
10. Asf1a plays a role in regulating IE genes by assembling chromatin onto histone-free viral DNA by 3 h postinfection with herpes simplex virus 1 PMID: 22951827
11. The authors propose that Codanin-1 acts as a negative regulator of Asf1 function in chromatin assembly. PMID: 22407294
12. Low ASF1A is associated with familial longevity. PMID: 22247756
13. HIRA plays a unique, ASF1a-independent role, which is required for the localization of HP1 PMID: 21347226
14. Identify marks on histones H3-H4 bound to Asf1 and changes induced upon replication stress. PMID: 20227376
15. model is proposed in which the synergism between hAsf1 and CAF-1 for nucleosome formation during DNA repair is achieved through a transient physical interaction allowing histone delivery from Asf1 to CAF-1 PMID: 11897662
16. NMR structure of the conserved core of hAsf1 A PMID: 15213445
17. Data suggest that Asf1 provides cells with a buffering system for histone excess generated in response to stalled replication and explains how cells maintain an "active" histone pool available during recovery from replication stresses. PMID: 15664198
18. Evidence of binding between a histone and one of its chaperones and genetic data suggesting that this interaction is important in both the DNA damage response and transcriptional silencing. PMID: 15840725
19. The N- and C-terminal regions of ASF1a and ASF1b determine the different affinities of these two proteins for HIRA, by contacting regions outside the HIRA B domain. CAF-1 p60 also uses B domain-like motifs for binding to ASF1a. PMID: 16980972
20. Studies provide evidence for TLK1B-mediated phosphorylation of Asf1 triggering DNA repair. PMID: 17054786

24. data link Asf1 chaperone function, histone supply, and replicative unwinding of DNA in chromatin; proposed that Asf1, as a histone acceptor and donor, handles parental and new histones at the replication fork via an Asf1-(H3-H4)-MCM2-7 intermediate PMID: 18096807
25. ASF1A and ASF1B play a role in the efficiency of nucleosome assembly in vivo in human cells. PMID: 18378699
