The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% 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 ab197902 at 1/250 dilution (shown in green) and ab6046 (Rabbit polyclonal to beta Tubulin) at 1μg/ml. This was followed by an incubation at room temperature for 1h with ab150088, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 594), pre-adsorbed, at 1μg/ml (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The protein SDHB also known as Succinate Dehydrogenase Complex Iron Sulfur Subunit B plays a mechanical role as a component of the succinate dehydrogenase (SDH) enzyme. This subunit has a molecular mass of approximately 30 kDa. SDHB is part of the mitochondrial inner membrane where it is expressed in high levels across various tissues including heart kidney and muscle. It contributes to the electron transport chain by facilitating the oxidation of succinate to fumarate an important step in energy production through the tricarboxylic acid (TCA) cycle.
Biological function summary

SDHB participates in the succinate dehydrogenase complex acting within both the TCA cycle and the electron transport chain. By transferring electrons to coenzyme Q it helps generate an electrochemical gradient important for ATP synthesis. This complex also called Complex II includes other subunits such as SDHA SDHC and SDHD. Their interactions ensure proper function of metabolic processes within mitochondria bridging the gap between foundational energy metabolism and complex cellular processes.

Pathways

SDHB plays an important role in cellular respiration and metabolic cycles. It resides in the TCA cycle and the mitochondrial electron transport chain connecting its function to energy generation pathways. Specifically SDHB relates closely to SDHA and coenzyme Q all working together to facilitate electron transfer and effective mitochondrial energy output. The transfer of electrons through this pathway highlights its essential contribution to maintaining cellular energy homeostasis.

SDHB mutations are associated with conditions such as paraganglioma and pheochromocytoma. These genetic alterations disrupt normal complex II function leading to the accumulation of succinate and succinate-related oncogenesis. In addition to causing tumor development defective SDHB is linked with familial paraganglioma syndromes. Its interaction with proteins such as SDHA and SDHD critical for the succinate dehydrogenase functionality highlights its significant role in maintaining metabolic balance and when defective contributing to disease pathogenesis.

Target data

Iron-sulfur protein (IP) subunit of the succinate dehydrogenase complex (mitochondrial respiratory chain complex II), responsible for transferring electrons from succinate to ubiquinone (coenzyme Q) (PubMed : 2902878). SDH also oxidizes malate to the non-canonical enol form of oxaloacetate, enol-oxaloacetate (PubMed : 1864383, PubMed : 2902878). Enol-oxaloacetate, which is a potent inhibitor of the succinate dehydrogenase activity, is further isomerized into keto-oxaloacetate (PubMed : 2902878).
