WebMay 6, 2024 · A novel class of small proteins, called micropeptides, has recently been discovered in the genome. These proteins, which have been found to play important roles in many physiological and cellular systems, are shorter than 100 amino acids and were overlooked during previous genome annotations. Discovery and characterization of more … WebMar 1, 2024 · DWORF is the only known endogenous peptide that activates SERCA ( Fig. 2 ). It is specifically expressed in heart and muscle cells and localizes to the SR membrane, like MLN. DWORF-Tg mice display significantly higher SERCA activity [ 31, 32].
