SKIP has been described as a transcriptional coregulator as well as a spliceosome component, but the relationship between these functions is not clear. We found that SKIP activated reporter gene expression from the basal promoters of viral origin. SKIP exhibited more prominent effect on the promoters with stronger activities, in an experiment employing a series of reporter constructs carrying different numbers of GC boxes. We also found that SKIP suppressed aberrant splicing at a cryptic splice donor site in the luciferase reporter gene. In addition, SKIP suppressed splicing of an extra intron created by a β-thalassemia mutation in the human β-globin gene. In the transfection experiment, an intronless reporter exhibited a higher level of expression, but was less significantly activated by SKIP, than the intron-containing reporter. These results indicate that SKIP affects gene expression by both transcriptional activation and regulation of pre-mRNA splicing.
