CC -!- FUNCTION: Necessary for the splicing of pre-mRNA. It is required for
CC formation of the earliest ATP-dependent splicing complex and interacts
CC with spliceosomal components bound to both the 5'- and 3'-splice sites
CC during spliceosome assembly. It also is required for ATP-dependent
CC interactions of both U1 and U2 snRNPs with pre-mRNA. Interacts with
CC other spliceosomal components, via the RS domains, to form a bridge
CC between the 5'- and 3'-splice site binding components, U1 snRNP and
CC U2AF. Binds to purine-rich RNA sequences, either 5'-AGSAGAGTA-3' (S=C
CC or G) or 5'-GTTCGAGTA-3'. Can bind to beta-globin mRNA and commit it to
CC the splicing pathway. The phosphorylated form (by SRPK2) is required
CC for cellular apoptosis in response to cisplatin treatment (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: In vitro, self-associates and binds SRSF1/SFRS1 (ASF/SF2),
CC SNRP70 and U2AF1 but not U2AF2. Binds SREK1/SFRS12. Interacts with
CC CCNL1 and CCNL2. Interacts with SCAF11. Interacts with ZRSR2/U2AF1-RS2.
CC Interacts with CCDC55 (via C-terminus). Interacts with BRDT (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Nucleus, nucleoplasm
CC {ECO:0000250}. Nucleus speckle {ECO:0000250}. Note=Phosphorylation by
CC SRPK2 provokes its redistribution from the nuclear speckle to
CC nucleoplasm. {ECO:0000250}.
CC -!- PTM: Extensively phosphorylated on serine residues in the RS domain.
CC Phosphorylated by SRPK2 and this causes its redistribution from the
CC nuclear speckle to nucleoplasm and controls cell fate decision in
CC response to cisplatin treatment. KAT5/TIP60 inhibits its
CC phosphorylation by preventing SRPK2 nuclear translocation (By
CC similarity). {ECO:0000250}.
CC -!- PTM: Acetylation on Lys-52 by KAT5/TIP60 promotes its proteasomal
CC degradation. This effect is counterbalanced by HDAC6, which positively
CC controls SRSF2 protein level by deacetylating it and preventing its
CC proteasomal degradation (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the splicing factor SR family. {ECO:0000305}.
