Tag Info

Tag type will be determined during the manufacturing process.

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.

Form

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.

Buffer before Lyophilization

Tris/PBS-based buffer, 6% Trehalose.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Troubleshooting and FAQs

Protein FAQs

Storage Condition

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

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.

Lead Time

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.

Notes

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

Target Background

Function

Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function. In response to cellular stress, up-regulated in distal tissues in a pqm-1-dependent manner, preventing protein misfolding and maintaining proteostasis. By stabilizing the receptor-type guanylate cyclase daf-11 or another signal transduction component that regulates cGMP levels, plays a role in dauer formation and chemotaxis to non-volatile and volatile attractants detected by AWC sensory neurons. Participates in the control of cell cycle progression at the prophase/metaphase transition in oocyte development by ensuring the activity of wee-1.3 kinase, which negatively regulates cdk-1 through its phosphorylation. Regulates yap-1 nuclear export after heat shock treatment.

Gene References into Functions

The study shows that a conserved tryptophan in the middle domain senses the interaction of Hsp90 with a stringent client protein and transfers this information via a cation-pi interaction with a neighboring lysine. PMID: 29662162
DAF-21 Ienterd this protein as newentry study explores the role and contribution of MAP Kinase pathway and its regulator protein DAF-21 involvement in the immunity against opportunistic pathogen P. mirabilis infection PMID: 27072109
The activity of protein phosphatase 5 towards native clients, such as glucocorticoid receptor, is modulated by the middle- and C-terminal domains of Hsp90. PMID: 26593036
Suppression of misfolding in muscle cells is achieved not only by enhanced expression of HSP90 in muscle cells but also by elevated expression of HSP90 (Daf-21) in intestine or neuronal cells. This cell-nonautonomous control of HSP90 expression relies upon transcriptional feedback between somatic tissues that is regulated by the FoxA transcription factor PHA-4. PMID: 23746847
Hsp90 (DAF-21) appears to participate in the maintenance of muscle structures as a transiently associated diffusible factor PMID: 21980476
DAF-21 indirectly regulates the meiotic prophase/metaphase transition during oocyte development by ensuring the normal function of WEE-1.3. PMID: 16466390
PA28 is likely to function in collaboration with Hsp90. PMID: 16650828

Tissue Specificity

In the embryo comma stage, expression is strongly detected in cells of the head region and less so in other areas. In early larvae, expressed in postembryonic germ cells derived from Z2 and Z3 cells and the head region, in both hermaphrodites and males. U
