RPRD1B Protein, Human (HEK293, N-His)

RPRD1B, is a necessary scaffolding protein that maintains genetic integrity by regulating resolution of R-loops at both the transcription termination and DNA double-strand break (DSB) repair levels. In endometrial cancers, RPRD1B accelerates cell cycle through up-regulating Cyclin D1, CDK4, and CDK6. In addition, RPRD1B enhancse transcription of CCND1 and promotes cell proliferation by interacting with RNA polymerase II. RPRD1B enhances the β-Catenin·TCF4 transcriptional activity in response to Wnt signaling^[1][2][3][4]. RPRD1B Protein, Human (HEK293, N-His) is the recombinant human-derived RPRD1B protein, expressed by HEK293 , with N-6*His labeled tag.

RPRD1B, also known as Ku70-binding protein 5-Hera or CREPT, is a necessary scaffolding protein that maintains genetic integrity by regulating resolution of R-loops at both the transcription termination and DNA double-strand break (DSB) repair levels^[1]. RPRD1B is upregulated in various cancers and regulates genome stability and transcription termination^[2]. In endometrial cancers, RPRD1B accelerates cell cycle through up-regulating Cyclin D1, CDK4, and CDK6 (main regulators of the G1/S phase transition during cell cycle)^[3]. In addition, RPRD1B enhancse transcription of CCND1 and promotes cell proliferation by interacting with RNA polymerase II. RPRD1B enhances the β-Catenin·TCF4 transcriptional activity in response to Wnt signaling^[4].

• 
  Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.
