Function
Polynucleotide kinase that can phosphorylate the 5'-hydroxyl groups of double-stranded RNA (dsRNA), single-stranded RNA (ssRNA), double-stranded DNA (dsDNA) and double-stranded DNA:RNA hybrids. dsRNA is phosphorylated more efficiently than dsDNA, and the RNA component of a DNA:RNA hybrid is phosphorylated more efficiently than the DNA component. Plays a key role in both tRNA splicing and mRNA 3'-end formation. Component of the tRNA splicing endonuclease complex: phosphorylates the 5'-terminus of the tRNA 3'-exon during tRNA splicing; this phosphorylation event is a prerequisite for the subsequent ligation of the two exon halves and the production of a mature tRNA (PubMed:24766809, PubMed:24766810). Its role in tRNA splicing and maturation is required for cerebellar development (PubMed:24766809, PubMed:24766810). Component of the pre-mRNA cleavage complex II (CF-II), which seems to be required for mRNA 3'-end formation. Also phosphorylates the 5'-terminus of exogenously introduced short interfering RNAs (siRNAs), which is a necessary prerequisite for their incorporation into the RNA-induced silencing complex (RISC). However, endogenous siRNAs and microRNAs (miRNAs) that are produced by the cleavage of dsRNA precursors by DICER1 already contain a 5'-phosphate group, so this protein may be dispensible for normal RNA-mediated gene silencing.

Notes
Succinate Dehydrogenase Activity Assay Kit (Colorimetric) (ab228560) is rapid, simple and high-throughput adaptable. In this assay, Succinate Dehydrogenase converts succinate to fumarate, and transfers the electron to an artificial electron acceptor (Probe), which changes the color from blue to a colorless product (depending upon the sample enzymatic activity). This assay kit can detect less than 0.1mU Succinate Dehydrogenase activity in a variety of samples.
The kit provides enough reagents for 100 assays using the methods as described.
This product is manufactured by BioVision, an Abcam company and was previously called K660 Succinate Dehydrogenase Activity Colorimetric Assay Kit. K660-100 is the same size as the 100 test size of ab228560.
Succinate Dehydrogenase (SDH) (EC 1.3.5.1) or succinate-coenzyme Q reductase (SQR) or respiratory complex II is an enzyme complex, which is bound to the inner mitochondrial membrane. SDH participates in both the citric acid cycle and electron transport chain. In mammals and many bacteria, SDH consists of 2 hydrophilic subunits, SDHA (flavoprotein) and SDHB (iron-sulfur protein) and 2 hydrophobic membrane anchor subunits: SDHC and SDHD. SDH oxidizes succinate to fumarate and transfers the electrons to ubiquinone. SDH deficiency in humans leads to a variety of phenotypes including Leigh syndrome, a neurometabolic disorder, tumor formation, and myopathy. Recent studies show that SDH can prevent the generation of ROS (reactive oxygen species); therefore, measurement of succinate dehydrogenase activity has wide applications.
Supplementary info

- Activity summary
Complex II also known as succinate dehydrogenase (SDH) or succinate-ubiquinone oxidoreductase plays an important mechanical role in the mitochondrial electron transport chain. It catalyzes the oxidation of succinate to fumarate while reducing ubiquinone to ubiquinol. The enzyme complex is approximately 140 kDa in mass and resides in the inner mitochondrial membrane. Complex II is expressed in most tissues particularly in high-energy demand tissues such as the heart and skeletal muscles.
- Biological function summary
Complex II functions as part of the larger electron transport chain complex and plays a role in the Krebs cycle. It links two critical metabolic pathways converting succinate to fumarate while transferring electrons to the electron transport chain. This makes it integral for proper cellular respiration and energy production. The complex consists of multiple subunits and utilizes co-factors like FAD and iron-sulfur clusters for enzymatic activity. It is also a part of the supercomplexes that optimize the efficiency of oxidative phosphorylation.
- Pathways
Complex II plays a significant role in both the citric acid cycle and oxidative phosphorylation. It acts as a connecting bridge between these two pathways facilitating the flow of electrons. Complex II works alongside other proteins such as complex I and complex III to maintain the electron transport chain's function and energy production. Succinate dehydrogenase transfers electrons within the chain directly affecting the generation of ATP by complex V (ATP synthase).
- Associated diseases and disorders
Dysfunction of complex II is associated with mitochondrial diseases and cancers. Mutations or deficiencies in its subunits can lead to conditions like Leigh syndrome and hereditary paraganglioma. These conditions frequently involve other mitochondrial proteins and complexes such as complex I which can exacerbate the electron transport chain dysfunction. In cancers alterations in succinate dehydrogenase activity can result in oncogenic metabolisms by falsely stabilizing hypoxia-inducible factors linking it further with the genetic and metabolic regulation.
