Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-U2AF65 antibody (AB37530)

IHC image of ab37530 staining in Human breast adenocarcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab37530, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

U2AF65 also known as U2 small nuclear RNA auxiliary factor 2 (U2AF2) is a splicing factor structured around 65 kilodaltons in mass. It interacts with RNA as part of the spliceosome to facilitate proper pre-mRNA splicing. The protein ensures the precise recognition and binding of the polypyrimidine tract at the 3' splice site. It is expressed in various human tissues playing an important role in RNA processing across different cell types.
Biological function summary

The U2AF65 protein contributes to the assembly of the spliceosome a major RNA-protein complex involved in splicing pre-messenger RNA. It works as part of the heterodimeric U2AF complex along with U2AF35 enhancing the precise selection of splice sites. This activity is essential to ensure accurate and efficient splicing which is necessary for proper gene expression and regulation.

Pathways

The activity of U2AF65 is an integral part of the RNA splicing pathway which plays a critical role in modulating gene expression. U2AF65 acts in coordination with other splicing factors such as SF1 and SF3B1 ensuring the correct assembly of the functional spliceosome. The accurate regulation of this pathway is essential for generating diversity in protein expression and for maintaining cell homeostasis.

Misregulation of U2AF65 activity has implications in diseases like cancer and spinal muscular atrophy. Alterations in the expression or function of U2AF65 can lead to aberrant splicing events which affect gene expression profiles. In cancer U2AF65 interacts with various oncogenes and tumor suppressor proteins potentially contributing to tumour progression. In spinal muscular atrophy alterations in splicing factors including U2AF65 influence the expression of survival motor neuron proteins intricately linking U2AF65 to the pathology of these conditions.

靶点信息

Plays a role in pre-mRNA splicing and 3'-end processing (PubMed : 17024186). By recruiting PRPF19 and the PRP19C/Prp19 complex/NTC/Nineteen complex to the RNA polymerase II C-terminal domain (CTD), and thereby pre-mRNA, may couple transcription to splicing (PubMed : 21536736). Induces cardiac troponin-T (TNNT2) pre-mRNA exon inclusion in muscle. Regulates the TNNT2 exon 5 inclusion through competition with MBNL1. Binds preferentially to a single-stranded structure within the polypyrimidine tract of TNNT2 intron 4 during spliceosome assembly. Required for the export of mRNA out of the nucleus, even if the mRNA is encoded by an intron-less gene. Represses the splicing of MAPT/Tau exon 10. Positively regulates pre-mRNA 3'-end processing by recruiting the CFIm complex to cleavage and polyadenylation signals (PubMed : 17024186).
