Review of post-translational modification of human serum albumin

Abstract

Abstract: Post-translational modifications (PTMs) may affect functions of human serum albumin. Here we review reports of novel PTMs of human serum albumin. One hundred twenty-three recently reported novel O-phosphorylation, glycation, methylation, carbonylation, and acetylation of albumin are reviewed. Potential impact of these PTMs on albumin functions is discussed. Knowledge of these PTMs of albumin is of importance for use of albumin in medical applications, e.g., in transfusion, drug formulations and remedies.
