Product Overview

Tag GST
Host Species Human
Accession Q13901
Synonym hC1D, LRP1, Rrp47, SUN-CoR, SUNCOR
Background C1D nuclear receptor corepressor belongs to the C1D family. It is a DNA binding and apoptosis-inducing protein.C1D nuclear receptor corepressorinteracts with TSNAX and DNA-PKcs. It acts as a corepressor for the thyroid hormone receptor. It is thought that C1D nuclear receptor corepressor regulates TRAX/Translin complex formation. It is expressed in kidney, heart, brain, spleen, lung, testis, liver and small intestine. It plays a role in the recruitment of the RNA exosome complex to pre-rRNA to mediate the 3'-5' end processing of the 5.8S rRNA; this function may include MPHOSPH6. It potentiates transcriptional repression by NR1D1 and THRB. C1D nuclear receptor corepressorcan activate PRKDC not only in the presence of linear DNA but also in the presence of supercoiled DNA. It also can induce apoptosis in a p53/TP53 dependent manner.

Gene Functions References

  1. C1D is associated with the DNA repair complex and may promote repair of ultraviolet irradiation-induced DNA damage. PMID: 20530579
  2. Results are consistent with a role for the exosome-associated protein C1D in the recruitment of the exosome to pre-rRNA to mediate the 3' end processing of the 5.8S rRNA. PMID: 17412707
  3. Anti-C1D autoantibodies were observed in patients with polymyositis-scleroderma overlap syndrome. PMID: 17599775
  4. TRAX enhances the DNA binding capacity of Translin, that binds to recombination regions in some malignancies. C1D interacts with TRAX following g-irradiation and prevents formation of TRAX/Translin complex, thereby inhibits any unwanted recombination. PMID: 11801738
  5. The C1D protein interacts with the catalytic subunit of DNA-PK and is a very effective substrate for DNA-PK in vitro. Moreover, C1D directs the activation of DNA-PK in a manner that does not require DNA termini, suggesting a role for C1D in DNA repair. PMID: 9679063

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
