The AF4/FMR2 family, member 4 ELISA kits listed below are analytical tools for measuring concentrations of AF4/FMR2 family, member 4 in various samples. AF4/FMR2 family, member 4 is an alternative name for the human AFF4 gene, which encodes the protein, ALF transcription elongation factor 4. It has been mentioned that AF4/FMR2 family, member 4 plays a role in the regulation of gene expression and spermatid development, among other functions. Structurally, the AFF4 protein is 1163 amino acid residues in length and 127.5 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. Other names for this target antigen include AF5Q31, CHOPS, and MCEF.
