S130A_ARATH | function | Subunit of the splicing factor SF3B required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B complex upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA. May also be involved in the assembly of the 'E' complex. Belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class of nuclear pre-mRNA intron (By similarity). Required for pollen and ovule development, especially during the transition from microspore to the bicellular stage in pollen development. Involved in the accumulation of QRT1 and QRT3 (PubMed:21680607). |
S130A_ARATH | similarity | Belongs to the RSE1 family. |
S130A_ARATH | tissue specificity | Expressed at low levels in roots, leaves, inflorescence and, to a lower extent, in siliques. |
