Summaries for U2AF1 Gene

Entrez Gene Summary for U2AF1 Gene

  • This gene belongs to the splicing factor SR family of genes. U2 auxiliary factor, comprising a large and a small subunit, is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. This gene encodes the small subunit which plays a critical role in both constitutive and enhancer-dependent RNA splicing by directly mediating interactions between the large subunit and proteins bound to the enhancers. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

CIViC summary for U2AF1 Gene

  • U2AF1 is one of several spliceosome complex genes frequently mutated in a variety of hematologic malignancies, particularly de novo myelodysplastic syndromes (MDS), as well as solid tumors such as lung and pancreatic cancers. Two hotspot mutations (S34 and Q157) occur within the two zinc-finger domains of the U2AF1 protein. These mutations have been associated with altered splicing patterns in vitro and in vivo. U2AF1 mutations in MDS have been associated with an increased risk of transformation to secondary acute myeloid leukemia, however, the impact of these mutations on overall survival has been an area of debate.

GeneCards Summary for U2AF1 Gene

U2AF1 (U2 Small Nuclear RNA Auxiliary Factor 1) is a Protein Coding gene. Diseases associated with U2AF1 include Myelodysplastic Syndrome and Myeloid Leukemia. Among its related pathways are mRNA Splicing - Major Pathway and RNA Polymerase II Transcription Termination. Gene Ontology (GO) annotations related to this gene include nucleic acid binding and nucleotide binding. An important paralog of this gene is U2AF1L5.

UniProtKB/Swiss-Prot for U2AF1 Gene

  • Plays a critical role in both constitutive and enhancer-dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3-splice site selection. Recruits U2 snRNP to the branch point. Directly mediates interactions between U2AF2 and proteins bound to the enhancers and thus may function as a bridge between U2AF2 and the enhancer complex to recruit it to the adjacent intron.

  • Myelodysplastic syndrome (MDS) [MIM:614286]: A heterogeneous group of closely related clonal hematopoietic disorders. All are characterized by a hypercellular or hypocellular bone marrow with impaired morphology and maturation, dysplasia of the myeloid, megakaryocytic and/or erythroid lineages, and peripheral blood cytopenias resulting from ineffective blood cell production. Included diseases are: refractory anemia (RA), refractory anemia with ringed sideroblasts (RARS), refractory anemia with excess blasts (RAEB), refractory cytopenia with multilineage dysplasia and ringed sideroblasts (RCMD-RS); chronic myelomonocytic leukemia (CMML) is a myelodysplastic/myeloproliferative disease. MDS is considered a premalignant condition in a subgroup of patients that often progresses to acute myeloid leukemia (AML). {ECO:0000269 PubMed:22158538, ECO:0000269 PubMed:25311244}. Note=The gene represented in this entry may be involved in disease pathogenesis. Mutation altering U2AF1 function in the context of specific RNA sequences can lead to aberrant alternative splicing of target genes, some of which may be relevant for MDS pathogenesis. {ECO:0000269 PubMed:25311244}.
