SRSF7

Function

Required for pre-mRNA splicing. Can also modulate alternative splicing in vitro. Represses the splicing of MAPT/Tau exon 10. May function as export adapter involved in mRNA nuclear export such as of histone H2A. Binds mRNA which is thought to be transferred to the NXF1-NXT1 heterodimer for export (TAP/NXF1 pathway); enhances NXF1-NXT1 RNA-binding activity. RNA-binding is semi-sequence specific.

Post-translational modifications

Extensively phosphorylated on serine residues in the RS domain.

Sequence Similarities

Belongs to the splicing factor SR family.

Tissue Specificity

Brain, liver, kidney and lung.

Cellular localization

Alternative names

SFRS7, SRSF7, Serine/arginine-rich splicing factor 7, Splicing factor 9G8
