PF3D7_0517300 serine/arginine-rich splicing factor 1

The RS domain localizes PfSR1 to the nucleus. IFAs showing the localization of PfSR1 wasectopically express fused to a myc epitope tag and detected using anti-myc antibodies. PfSR1 (green); DAPI staining (blue); developmental stages are indicated on the left. (A) Cellular localization of PfSR1-myc. PfSR1 shuttles between the nucleus and cytoplasm. The cytoplasmic location is restricted to regions that are outside the parasite’s food vacuole. the nuclear location of PfSR1 at early ring stages is in a distinct punctuated pattern mainly at the nuclear periphery and is not equally spread all over the nucleus.
