Anti-CELF4 antibodies are used in the immunodetection of the protein CUGBP Elav-like family member 4. In humans, the canonical protein has a reported length of 486 amino acid residues and a mass of 52 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 5 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the CELF/BRUNOL protein family, CELF4 is known to be an RNA-binding protein implicated in the regulation of pre-mRNA alternative splicing. Synonyms for this target antigen include LYST-interacting protein LIP9, RNA-binding protein BRUNOL4, bruno-like 4, RNA binding protein, bruno-like protein 4, and CUG-BP- and ETR-3-like factor 4. CELF4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of CELF4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
