Descripción general
RPB1 (RNA polymerase II subunit B1) is the catalytic component of RNA polymerase II which synthesizes mRNA and non-coding RNAs. During transcription, elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of RPB1, which acts as an assembly platform for factors regulating transcription initiation, elongation, termination and mRNA processing. Phosphorylation occurs mainly at residues ′Ser-2′ and ′Ser-5′ of the tandem 7 residue repeats in the C-terminal domain (CTD), which activates Pol II. This phosphorylation also can occur at ′Ser-7′ of the heptapepdtide repeat. This antibody recognizes the ′Ser-5′ CTD residue of RPB1.
Especificidad
This antibody recognizes RNA Polymerase II subunit B1 phosphorylated at Ser5 of the C-terminus domain (CTD).
Inmunógeno
