Abstract:
SR proteins are a family of splicing factors important for splice site recognition and spliceosome assembly. Their ability to bind to RNA and to interact with proteins as well identifies them as important players in splice site choice and alternative splicing. Plants possess twice as many SR proteins as animals, and some of the subfamilies are plant specific. Arabidopsis SR proteins are involved in different aspects of plant growth and development as well as in responses to environmental cues. The plant-specific subfamilies have been shown to be regulated by alternative splicing events, which are highly conserved in evolution. The tight regulation of splicing factors by alternative splicing might allow coordinated responses of their target genes.
