Gene Information

human ... TFB2M(64216)

General description

TFB2M is a mitochondrial transcription factor that regulates the expression of SERCA2 gene in rat cardiomyocytes. It is also known to induce the transcription of human mtDNA.
Rabbit Anti-TFB2M (AB1) antibody recognizes human and rat TFB2M.

Immunogen

Synthetic peptide directed towards the N terminal region of human TFB2M

Application

Rabbit Anti-TFB2M (AB1) antibody is suitable for western blot (1.25 μg/ml) and IHC (4-8 μg/ml) applications.

Biochem/physiol Actions

TFB2M is a S-adenosyl-L-methionine-dependent methyltransferase which specifically dimethylates mitochondrial 12S rRNA at the conserved stem loop. It is also required for basal transcription of mitochondrial DNA, probably via its interaction with POLRMT and TFAM. It stimulates transcription independently of the methyltransferase activity. Compared to TFB1M, it activates transcription of mitochondrial DNA more efficiently, while it has less methyltransferase activity.

Sequence

Synthetic peptide located within the following region: ECNPGPGILTQALLEAGAKVVALESDKTFIPHLESLGKNLDGKLRVIHCD

Physical form

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.

Sarco(endo)plasmic reticulum Ca²(+)-ATPase 2a (SERCA2a) transports Ca²(+) by consuming ATP produced by mitochondrial respiratory chain enzymes. Messenger RNA (mRNA) for these enzymes is transcribed by mitochondrial transcription factors A (TFAM) and B2 (TFB2M). This study examined whether TFAM and TFB2M

Characterization of the basic transcription machinery of mammalian mitochondrial DNA (mtDNA) is of fundamental biological interest and may also lead to therapeutic interventions for human diseases associated with mitochondrial dysfunction. Here we report that mitochondrial transcription factors B1 (TFB1M) and
