Product Overview
This rabbit polyclonal antibody detects dimethyladenosine transferase 2, mitochondrial (gene TFB2M) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 45.3 kDa, and the supplier reports an observed band at about 38 kDa.
TFB2M is a mitochondrial transcription factor that works with TFAM and the RNA polymerase POLRMT to start transcription of mitochondrial DNA. It helps open promoter DNA for the polymerase, and it is also related to rRNA methyltransferases, reflecting its origin from a bacterial enzyme.
