產品描述：
Recombinant Human RPA1 expression in E.coli requires the insertion of the target DNA fragment into an E.coli expression vector, routinely a plasmid vector, and the transferral of this vector into E.coli cells. The cells are then cultured and induced to express this RPA1 protein.?The cells are harvested by centrifugation, samples prepared and proteins detected by polyacrylamide gel electrophoresis and subsequent staining of the gel with Coomassie Brilliant Blue or silver stain or by immunoblotting. The RPA1 protein expression in E.coli?is highly scalable and can be adjusted from the bacterial colony to conical flasks for liquid cultures, to fermentation reaction chambers.
RPA1 is a protein coding gene that encodes Replication protein A 70 kDa DNA-binding subunit. According to some studies, RPA1 may have the following features.
The function of Rpa1 in DNA metabolism is critical for maintaining chromosomal stability and suppressing tumors. Binding of RPA1 to NRF2 switches ARE-dependent transcriptional activation to ARE-NRE-dependent repression. The acetylation state of RPA1 plays a critical role in repairing DNA damage through NER. RPA1 has multiple roles in the body, playing a role in DNA replication, repair and recombination. The physical interaction between Rfc4 and Rpa1N is required for both effects. K163 acetylation of RPA1 plays a key role in repairing UV-induced DNA damage. -

功能：As part of the heterotrimeric replication protein A complex (RPA/RP-A), binds and stabilizes single-stranded DNA intermediates, that form during DNA replication or upon DNA stress. It prevents their reannealing and in parallel, recruits and activates different proteins and complexes involved in DNA metabolism. Thereby, it plays an essential role both in DNA replication and the cellular response to DNA damage. In the cellular response to DNA damage, the RPA complex controls DNA repair and DNA damage checkpoint activation. Through recruitment of ATRIP activates the ATR kinase a master regulator of the DNA damage response. It is required for the recruitment of the DNA double-strand break repair factors RAD51 and RAD52 to chromatin in response to DNA damage. Also recruits to sites of DNA damage proteins like XPA and XPG that are involved in nucleotide excision repair and is required for this mechanism of DNA repair. Plays also a role in base excision repair (BER) probably through interaction with UNG. Also recruits SMARCAL1/HARP, which is involved in replication fork restart, to sites of DNA damage. May also play a role in telomere maintenance. As part of the alternative replication protein A complex, aRPA, binds single-stranded DNA and probably plays a role in DNA repair. Compared to the RPA2-containing, canonical RPA complex, may not support chromosomal DNA replication and cell cycle progression through S-phase. The aRPA may not promote efficient priming by DNA polymerase alpha but could support DNA synthesis by polymerase delta in presence of PCNA and replication factor C (RFC), the dual incision/excision reaction of nucleotide excision repair and RAD51-dependent strand exchange.
