Anti-RNA Polymerase II Antibody, clone ARNA-3

半岛bd体育手机客户端 说明

一般描述

DNA-directed RNA polymerase II subunit RPB1 (EC 2.7.7.6; UniProt P04052; also known as DNA-directed RNA polymerase III largest subunit, RNA polymerase II subunit B1) is encoded by the RpII215 (also known as CG1554) gene (Gene ID 32100) in drosophila melanogaster (fruit fly). RNA polymerase II (Pol II) is a multi-subunit enzyme responsible for the transcription of protein-coding genes. Transcription initiation requires recruitment of the complete transcription machinery to a promoter via solicitation by activators and chromatin remodeling factors. Pol II can coordinate 10 to 14 subunits. This complex interacts with the promoter regions of genes and a variety of elements and transcription factors. The DNA binding domain of the polymerase is a groove where TFIIB orients the DNA for unwinding and transcription.

特异性

Broad species cross-reactivity expected due to sequence homology.
ARNA-3 is excellent for detection of transcription activity, e.g. puffs in polytene chromosomes. Reacts with RNA polymerase II in biological materials. Reactive polypeptides after SDS-PAGE: 200 kDa band of nonphosphorylated and 240 kDa band of phosphorylated Pol IIA.

免疫原

Purified Drosophila RNA polymerase II
Epitope: Amino acids 794-822

应用
