== Function ==
 +
[https://www.uniprot.org/uniprot/SPF45_HUMAN SPF45_HUMAN] Splice factor that binds to the single stranded 3'AG at the exon/intron border and promotes its utilization in the second catalytic step. Involved in the regulation of alternative splicing and the utilization of cryptic splice sites. Promotes the utilization of a cryptic splice site created by the beta-110 mutation in the HBB gene. The resulting frameshift leads to sickle cell anemia.<ref>PMID:12015979</ref>

== Publication Abstract from PubMed ==
 +
The U2AF-homology motif (UHM) mediates protein-protein interactions between factors involved in constitutive RNA splicing. Here we report that the splicing factor SPF45 regulates alternative splicing of the apoptosis regulatory gene FAS (also called CD95). The SPF45 UHM is necessary for this activity and binds UHM-ligand motifs (ULMs) present in the 3' splice site-recognizing factors U2AF65, SF1 and SF3b155. We describe a 2.1-A crystal structure of SPF45-UHM in complex with a ULM peptide from SF3b155. Features distinct from those of previously described UHM-ULM structures allowed the design of mutations in the SPF45 UHM that selectively impair binding to individual ULMs. Splicing assays using the ULM-selective SPF45 variants demonstrate that individual UHM-ULM interactions are required for FAS splicing regulation by SPF45 in vivo. Our data suggest that networks of UHM-ULM interactions are involved in regulating alternative splicing.
