Abstract excerpt

Serine/arginine-rich (SR) proteins are essential splicing factors in animals, where their mutations often cause widespread splicing defects and carcinogenesis. The plant SR subfamily proteins are homologous to the well-studied human SR splicing factor 1, but their roles remain unclear. Here, we characterize the Arabidopsis SR subfamily genes: SR30, SR34, SR34a, and SR34b. We show that GFP-tagged SR30, SR34, and...
