Tissue-specific splicing factor with potential implication in the regulation of alternative splicing during neuron and germ cell differentiation. Antagonizes SRSF1-mediated BCL-X splicing. May affect the choice of alternative 5' splice sites by binding to specific sequences in exons and antagonizing the SR protein SRSF1.
Subcellular locations: Nucleus, Nucleoplasm, Nucleus speckle
Enriched in SRSF2-containing splicing speckles; shuttles between nucleoplasm and speckles.
Expressed in brain, hippocampus, prefrontal cortex, cerebellum, spinal cord, testis, mammary gland, spleen and kidney. Also expressed in fetal brain.
