What is a short protein? Exploring microproteins and micropeptides

Historically, many genome sequencing projects set an arbitrary length threshold of 100 amino acids for protein-coding genes, inadvertently overlooking a vast class of small, functional proteins. A short protein, often called a microprotein or micropeptide, is a polypeptide chain typically consisting of 100 or fewer amino acids that serves critical biological functions in organisms.
