  sub:_6 prov:value """A strongly labeled doublet (Fig. 6, band B) corresponds to the relative position of
PRP4K, a finding consistent with the reported ability of mammalian PRP4K homologues
to autophosphorylate (19, 27). Two other prominently labeled proteins correspond
in size to BRG1 and PRP6 (Fig. 6, bands A and C, respectively). To confirm
that these proteins were indeed BRG1 and PRP6, we carried out kinase assays with
BRG1 and PRP6 IP complexes, which also contain coimmunoprecipitated PRP4K (Fig.
5). These immunoprecipitates do exhibit kinase activity, and both phosphorylated
PRP6 and BRG1 are much more intense in their respective IP reactions, reflecting
the relative increase in each substrate for PRP4K.""" ;
