SF3A3 is one of the components of the SF3a splicing factor complex of the mature U2 snRNP (small nuclear ribonucleoprotein particle). In yeast, SF3a shows a bifurcated assembly structure of three subunits, Prp9 (subunit 3), Prp11 (subunit 2) and Prp21 (subunit 1). Prp9 and Prp21 were not thought to interact with each other but the alpha1 helix of Prp9 does make important contacts with the SURP2 domain of Prp21, thus the two do interact via a bidentate-binding mode. Prp9 harbours a major binding site for stem-loop IIa of U2 snRNA [1].	Domain

This domain represents the C-terminal region of the Replication stress response SDE2, a genome surveillance factor. It contains the DNA-binding SAP domain, frequently found in proteins involved in DNA repair. SDE2 C-terminal domain must be cleaved from its N-terminal at a diglycine motif within the ubiquitin-like fold, after Proliferating cell nuclear antigen (PCNA) interaction. This generates a functional protein that negatively regulates damage-inducible PCNA monoubiquitination, which then is proteolytically degraded to allow S phase progression and replication fork recovery in response to DNA damage [1].

This domain is found in eukaryotes. This domain is about 30 amino acids in length. This domain has a single completely conserved residue Y that may be functionally important. SF3a60 makes up the SF3a complex with SF3a66 and SF3a120. This domain is the binding site of SF3a60 for SF3a120. The SF3a complex is part of the spliceosome, a protein complex involved in splicing mRNA after transcription.	Domain
