Abstract:
Post-translational modifications (PTMs) of proteins influence protein degradation, protein-
protein interactions, expression of genes, and intracellular signal transduction, thereby regulating
major life processes. Among the PTMs occurring within the cytoplasm and nucleus, the most
commonly studied one is the arginine methylation of proteins catalyzed by PRMTs. PRMT1 is the
most excellent and extensively studied member of the PRMT family. PRMT1 occurs in various isoforms,
and the unique sequence splicing of each of these isoforms encodes differential proteins that
exhibit different cellular localization, substrate specificity, and enzyme activity. In addition to
methylating histones, PRMT1 also methylates a large number of non-histone substrates that regulate
a broad range of cellular processes. In recent years, research has revealed an increasing number
of pathological diseases caused by the misregulation and aberrant expression of PRMT1, demonstrating
the potential of PRMT1 as an effective biomarker for drug targets. In this context, the
present study discusses the structural characteristics and the biological functions of PRMT1.
Practical Applications: Several diseases originate from aberrant post-translational modifications.
The misregulation of the arginine methylation of proteins, which is regulated by PRMTs and influences
a series of cellular activities, leads to developmental abnormalities and physiological diseases.
PRMT1, which accounts for 85% of the activity of PRMTs, is involved in several cellular processes
occurring in various diseases. Multiple inhibitors have been developed and studied for their
potential as biomarkers and suitable drug targets in clinical application. The present report summarizes
the findings of the most recent studies focusing on the structural characteristics, splicing,
substrates, and biological functions of PRMT1, to contribute to future research for deciphering the
molecular mechanisms of PRMT1 and drug improvement.
