Description

General description

Monoclonal Anti-U2AF⁶⁵ (mouse IgG2b isotype) is derived from the MC3 hybridoma produced by the fusion of mouse myeloma cells (Ag8.653 cells) and splenocytes from BALB/c mice immunized with recombinant human U2AF⁶⁵. U1, U2, U4/U6, and U5 are small nuclear riboprotein (snRNPs) that are major subunits of spliceosomes. Spliceosomes also contain non snRNPs proteins such as alternative splicing factor/splicing factor 2 (ASF/SF2), 35 kDa spliceosomal component (SC-35) and U2 snRNP auxiliary splicing factor (U2AF). U2 snRNP auxiliary factor 65 kDa (U2AF⁶⁵) is a splicing factor which has three C-terminal RNA recognition motifs (RRMs) and an N-terminal arginine/serine-rich (RS) domain. This gene is mapped to human chromosome 19q13.42. Splicing factor U2AF⁶⁵kDa subunit is a non-snRNP protein component of spliceosome complexes.

Immunogen

recombinant human U2AF⁶⁵.

Application

Monoclonal Anti-U2AF⁶⁵ antibody produced in mouse has been used in:

• RNA immunoprecipitation
• immunoblotting
• chromatin immunoprecipitation (ChIP)
• enzyme-linked immunosorbent assay (ELISA)
• immunohistochemistry
• immunocytochemistry
• immunoelectron microscopy

Biochem/physiol Actions

U2 snRNP auxiliary factor 65 kDa (U2AF⁶⁵)/U2AF2 helps to supply the small nuclear ribonucleoprotein (snRNP) U2, which is subunit of the spliceosome. It can induce the exclusion of alternative exons. U2AF⁶⁵ primarily regulates the splicing of pre-mRNA. The serine-rich (RS) repeats at the N-terminal region act as a signalling factor for nuclear localization. (U2AF⁶⁵) and (U2AF³⁵) are components of the splicing factor U2AF that transports between the cytoplasm and the nucleus.

Physical form
