Gene : SAP130a A. thaliana

DB identifier  ? AT3G55200 Secondary Identifier  ? locus:2100616
Name  ? spliceosome-associated protein 130 a Brief Description  Cleavage and polyadenylation specificity factor (CPSF) A subunit protein
TAIR Computational Description  Cleavage and polyadenylation specificity factor (CPSF) A subunit protein;(source:Araport11)
TAIR Curator Summary  Encodes a spliceosomal protein that is required for proper reproduction. RNAi lines display low pollen viability,caused by a defect in the transition from microspore to bicellular stage during pollen development.
TAIR Short Description  Cleavage and polyadenylation specificity factor (CPSF) A subunit protein
TAIR Aliases  AtSAP130a, SAP130a

Type Comment Proteins
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.
