19553338 These results indicate that ICP27 RGG box methylation regulates interaction ALY and SRPK1 proteins.
19477182 while local RS/SR content steers regional preferences in the RS domain, distal contacts with SRPK1 guide initiation and directional phosphorylation within these regions.
19240134 SRPK1, a ubiquitously expressed SR protein-specific kinase, directly binds to the cochaperones Hsp40/DNAjc8 and Aha1, which mediate dynamic interactions of the kinase with the major molecular chaperones Hsp70 and Hsp90 in mammalian cells
