(A) Western blot analysis from HeLa cells co-expressing either G14 or G14A5 with one or both SRα and SRβ. b/a indicates the increase in SR subunit expression standardized to β-actin.
(B) Cellular localization of SRα and SRβ. Immunofluorescent images from HeLa cells expressing G14A5 and both SR subunits labeled with anti-SRα and anti-SRβ antibodies.
(C) SEAP secretion of cells co-expressing either G14A5 or, as controls, G14 or GFP and one or both SR subunits.
