Description : | This gene encodes the largest subunit of the heterotrimeric Replication Protein A (RPA) complex, which binds to single-stranded DNA (ssDNA), forming a nucleoprotein complex that plays an important role in DNA metabolism, being involved in DNA replication, repair, recombination, telomere maintenance, and co-ordinating the cellular response to DNA damage through activation of the ataxia telangiectasia and Rad3-related protein (ATR) kinase. The nucleoprotein complex protects the single-stranded DNA from nucleases, prevents formation of secondary structures that would interfere with repair, and co-ordinates the recruitment and departure of different genome maintenance factors. This subunit contains four oligonucleotide/oligosaccharide-binding (OB) domains, though the majority of ssDNA binding occurs in two of these domains. The heterotrimeric complex has two different modes of ssDNA binding, a low-affinity and high-affinity mode, determined by which ssDNA binding domains are utilized. The different binding modes differ in the length of DNA bound and in the proteins with which it interacts, thereby playing a role in regulating different genomic maintenance pathways. |
Source : | E. coli |
Species : | Human |
Tag : | N-His&GST |
Form : | Freeze-dried powder |
Molecular Mass : | Predicted Molecular Mass: 72 kDa |
Protein length : | Asp18-Pro403 |
Purity : | > 97% |
Applications : | Positive Control; Immunogen; SDS-PAGE; WB. |
Stability : | The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 centigrade for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition. |
Storage : | Avoid repeated freeze/thaw cycles. Store at 2-8 centigrade for one month. Aliquot and store at -80 centigrade for 12 months. |
Storage Buffer : | PBS, pH7.4, containing 0.01% SKL, 1mM DTT, 5% Trehalose and Proclin300. |
Reconstitution : | Reconstitute in 20mM Tris, 150mM NaCl (pH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex. |

Q&As (6)
Ask a questionRPA1 protein is involved in important steps such as pairing, redox, and fusion in DNA recombination, and is necessary to effectively maintain genome integrity and stability.
RPA1 protein participates in DNA damage repair, growth and development in embryonic development, and has a role in maintaining the genome in embryos.
Since RPA1 protein plays an important role in DNA oxidative damage repair, it can be used as a marker of the degree of DNA oxidative damage to monitor and detect the risk of related diseases.
Although RPA1 protein is not a factor directly involved in DNA methylation modification, it may be involved in DNA methylation by participating in processes such as DNA damage repair, chromatin structure, and regulation of gene expression.
Studies have shown that RPA1 protein is involved in processes such as insulin secretion and regulation of β cell function in diabetes, and may become a new target for therapeutic strategies.
The RPA1 protein is involved in DNA damage repair and cell cycle in the immune system, and studies have found that it may be involved in processes such as immune response and pattern recognition.
