ab47517 staining mtTFA in HeLa cells. The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% PBS-Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at 4°C with ab47517 at 5µg/ml and ab7291, Mouse monoclonal [DM1A] to alpha Tubulin - Loading Control. Cells were then incubated with ab150081, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 488), pre-adsorbed at 1/1000 dilution (shown in green) and ab150120, Goat polyclonal Secondary Antibody to Mouse IgG - H&L (Alexa Fluor® 594), pre-adsorbed at 1/1000 dilution (shown in pseudocolour magenta). Nuclear DNA was labelled with DAPI (shown in blue).

Also suitable in cells fixed with 4% paraformaldehyde (10 min).

Image was acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown.

Western blot - Anti-mtTFA antibody - Mitochondrial Marker (AB47517)

This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab47517 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.

MtTFA also known as mitochondrial transcription factor A or TFAM is an important element in mitochondrial DNA regulation. It plays a pivotal role in maintaining mitochondrial genome integrity and ensuring proper mitochondrial function. This protein weighing approximately 25 kDa is expressed within the mitochondria. It binds to the mitochondrial DNA facilitating the transcription and replication processes ensuring the correct functioning of cellular energy metabolism.
Biological function summary

MtTFA is essential for mitochondrial DNA packaging and transcriptional activation. It acts as a binding factor that organizes the mtDNA into a nucleoid-like structure providing protection and stability. MtTFA functions as part of a larger multi-protein complex that includes mitochondrial RNA polymerase ensuring proper transcription of mitochondrial genes. These activities are critical for normal energy production and mitochondrial biogenesis.

Pathways

The mtTFA protein is integral to the oxidative phosphorylation and mitochondrial biogenesis pathways. It orchestrates the expression of genes critical for these pathways alongside related proteins like NRF2 and PGC-1α. MtTFA ensures effective mitochondrial function by modulating the transcription of key mitochondrial-encoded components necessary for electron transport and ATP synthesis thereby sustaining cellular energy balance.

MtTFA dysregulation is associated with mitochondrial diseases and neurodegenerative disorders. Abnormal mtTFA activity disrupts mitochondrial DNA maintenance potentially leading to conditions like mitochondrial myopathy. It is also linked with proteins such as POLG which are involved in mitochondrial DNA replication. Understanding mtTFA's role in these pathologies highlights its importance as a target in therapeutic strategies aimed at restoring mitochondrial function and preventing disease progression.

Target data

Binds to the mitochondrial light strand promoter and functions in mitochondrial transcription regulation (PubMed : 29445193, PubMed : 32183942). Component of the mitochondrial transcription initiation complex, composed at least of TFB2M, TFAM and POLRMT that is required for basal transcription of mitochondrial DNA (PubMed : 29149603). In this complex, TFAM recruits POLRMT to a specific promoter whereas TFB2M induces structural changes in POLRMT to enable promoter opening and trapping of the DNA non-template strand (PubMed : 20410300). Required for accurate and efficient promoter recognition by the mitochondrial RNA polymerase (PubMed : 22037172). Promotes transcription initiation from the HSP1 and the light strand promoter by binding immediately upstream of transcriptional start sites (PubMed : 22037172). Is able to unwind DNA (PubMed : 22037172). Bends the mitochondrial light strand promoter DNA into a U-turn shape via its HMG boxes (PubMed : 1737790). Required for maintenance of normal levels of mitochondrial DNA (PubMed : 19304746, PubMed : 22841477). May play a role in organizing and compacting mitochondrial DNA (PubMed : 22037171).
