Argonautes are needed for miRNA-induced silencing and contain two conserved RNA binding domains: a PAZ domain that can bind the single stranded 3' end of the mature miRNA and a PIWI domain that structurally resembles ribonuclease-H and functions to interact with the 5' end of the guide strand. They bind the mature miRNA and orient it for ...

In molecular biology, miR-137 (or microRNA-137) is a short non-coding RNA molecule that functions to regulate the expression levels of other genes by various mechanisms. miR-137 is located on human chromosome 1p22 and has been implicated to act as a tumor suppressor in several cancer types including colorectal cancer, squamous cell carcinoma and melanoma via cell cycle control.
A diagram of how mRNA is used to create polypeptide chains. Ribosomal RNA (rRNA) is the catalytic component of the ribosomes. The rRNA is the component of the ribosome that hosts translation. Eukaryotic ribosomes contain four different rRNA molecules: 18S, 5.8S, 28S and 5S rRNA.
When Ambros and Ruvkun compared the sequence of the lin-4 miRNA and the lin-14 3’ untranslated region, they discovered that the lin-4 RNA base pairs with conserved bulges and loops to the 3’ untranslated region of the lin-14 target mRNA, and that the lin-14 gain of function mutations delete these lin-14 complementary sites to relieve the ...
In Jan. 2023, I wrote about my 10 top stocks to buy for the new year. I ended up pretty proud of my list because if you'd invested $1,000 in each of the 10 stocks the day the article was published ...
Ariana Grande, Cynthia Erivo and why cruel body comments around 'Wicked' need to stop. She continued: "I've heard every version of it, of what's wrong with me, and then you fix it, and then it's ...
Anti-miRNA oligonucleotides (also known as AMOs) have many uses in cellular mechanics. These synthetically designed molecules are used to neutralize microRNA function in cells for desired responses. miRNA are complementary sequences (≈22 bp) to mRNA that are involved in the cleavage of RNA or the suppression of the translation.
