In eukaryotes, miR-5 is a microRNA with sequence complementarity to the 3 UTR of the mRNA transcript encoded by the UCD gene. The UCD gene encodes for a protein that acts as an allosteric activator of the protein p101. The p101 protein is a histone acetyl transferase (HAT) which is an enzyme that acetylates histones when the protein is in its active form A different lung cancer cell line is found to have significantly decreased amounts of histone acetylation. Which...
