Small peptides of 100 amino acids or fewer are encoded by small open reading frames (smORFs) and mediate key physiological functions in animals and humans. smORFs constitute 99% of transcribed, but ...

There are some genes that can promote cancer; they are sometimes called oncogenes, and in tumor cells, mutations are often found in these genes. When they are functioning normally, oncogenes are often ...

Researchers have uncovered a vast new class of previously unrecognized mammalian genes that do not encode proteins, but instead function as long RNA molecules, and seem to play critical roles in both ...
