CC -!- FUNCTION: Subunit of the splicing factor SF3B required for 'A' complex
CC assembly formed by the stable binding of U2 snRNP to the branchpoint
CC sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B
CC complex upstream of the branch site is essential, it may anchor U2
CC snRNP to the pre-mRNA. May also be involved in the assembly of the 'E'
CC complex. Belongs also to the minor U12-dependent spliceosome, which is
CC involved in the splicing of rare class of nuclear pre-mRNA intron (By
CC similarity). Required for pollen and ovule development, especially
CC during the transition from microspore to the bicellular stage in pollen
CC development. Involved in the accumulation of QRT1 and QRT3
CC (PubMed:21680607). {ECO:0000250|UniProtKB:Q15393,
CC ECO:0000269|PubMed:21680607}.
CC -!- SUBUNIT: Identified in the spliceosome C complex. Component of the
CC U11/U12 snRNPs that are part of the U12-type spliceosome. Component of
CC splicing factor SF3B complex. {ECO:0000250|UniProtKB:Q15393}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q15393}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, leaves, inflorescence and, to a
CC lower extent, in siliques. {ECO:0000269|PubMed:21680607}.
CC -!- DISRUPTION PHENOTYPE: The double mutant sap130a sap130b displays a
CC slight reduction in the size of aerial organs and in the number of
CC lateral roots, and is impaired in reproduction due to a reduced
CC production of viable pollen and impaired female reproductive organs.
CC Defect in the transition from microspore to the bicellular stage in
CC pollen development. Reduced expression of QRT1 and QRT3.
CC {ECO:0000269|PubMed:21680607}.
CC -!- SIMILARITY: Belongs to the RSE1 family. {ECO:0000305}.
