Function

RNase A (previously sold as Biovision's M1517) is an endoribonuclease that specifically cleaves RNA at the phosphodiester bond between the 3’ phosphate group of a pyrimidine nucleotide and 5’-ribose of an adjacent nucleotide.

The highest activity is demonstrated with single stranded RNA. The recombinant enzyme is identical to the native RNase A in amino acid sequence, structure and specifications.

At low salt concentrations (0 to 100 mM NaCl), RNase A cleaves single-stranded and double-stranded RNA as well the RNA strand in RNA-DNA hybrids. However, at NaCl concentrations of 0.3 M or higher, RNase A specifically cleaves single-stranded RNA.

Precipitation may occur at high concentrations (>10 mg/mL) of the enzyme and RNase A has a high affinity to glass surfaces.

The enzyme is inhibited by diethyl pyrocarbonate (DEPC), guanidinium salts, β-mercaptoethanol, heavy metals and RNase-inhibitors.

In order to remove the enzyme from a sample, perform a separation with spin columns or several phenol/chloroform extractions.

Special care and precautions should be taken in the lab with this enzyme to ensure cross contamination with RNA work does not occur.

Activity summary

Ribonuclease A also known as RNase A is a type of ribonuclease enzyme known for its ability to cleave RNA molecules. This enzyme specifically catalyzes the endonucleolytic cleavage of RNA to produce 3'-phosphates and 3'-phosphooligonucleotides terminated by cytidine or uridine. RNase A has a molecular mass of approximately 13.7 kDa and is primarily found in the pancreas of bovines. This protein plays a significant role in RNA metabolism and is often utilized in laboratory research for this purpose.

Biological function summary

Ribonuclease A plays an important role in RNA processing and degradation contributing to the regulation of cellular RNA levels. This enzyme does not operate as part of a larger complex but acts independently to degrade single-stranded RNA. The function of RNase A is essential for maintaining cellular homeostasis by controlling the quantity and quality of the cellular RNA ensuring proper turnover and preventing the accumulation of defective or unnecessary RNA molecules.

Pathways

Ribonuclease A is involved in the RNA degradation pathway which is critical for normal cellular function and gene expression regulation. It collaborates with other nucleases to ensure efficient RNA turnover. RNase A is closely related to proteins like RNase 1 and RNase 5 which also participate in RNA metabolism. Participation of RNase A in this pathway highlights its importance in the regulation of genetic information flow from DNA to RNA.

Associated diseases and disorders

The malfunction or dysregulation of Ribonuclease A can impact diseases such as cancer and cystic fibrosis. In cancer aberrant RNase A activity can influence RNA levels contributing to unchecked cell proliferation. Moreover RNase A is connected to the inflammation seen in cystic fibrosis via its impact on RNA turnover and immune system signaling. RNase A interactions with proteins such as angiogenin which displays similar enzymatic properties further exemplify its involvement in disease-related pathways.
