Protein arginine methyltransferase 1 (PRMT1) is the major arginine methyltransferase, which catalyzes the addition of one or two methyl groups to the arginine residues of its substrate proteins. The best-known substrate for PRMT1 is histone, while more and more non-histone proteins are now found to be methylated by PRMT1. Dysregulation of PRMT1 is reported in several human cancer types. However, its biological roles in human pancreatic cancer initiation and development are still unclear. In the first part of this study, I found that the expression level of PRMT1 was elevated in both human and mouse pancreatic cancer tissues in immunohistochemistry ...

Arginine residues can be modified in three different ways to produce asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), and monomethylarginine (MMA). These modifications are catalyzed by a family of nine protein arginine methyltransferases (PRMT1-9), which are of three types (I, II, and III). The majority of Type I enzymes asymmetrically dimethylate Glycine- and Arginine-rich (GAR) motifs, except for PRMT4, which methylates Proline-, Glycine-, and Methionine-rich (PGM) motifs. The same substrates (GAR or PGM motifs) can also be dimethylated by PRMT5 in a symmetric fashion. However, it is not clear whether there are dedicated residues within these motifs for ADMA and SDMA ...
