These E1AF ELISA kits are immunodetection tools for measuring the levels of E1AF in biological samples. E1AF is an alias of the human ETV4 gene, which encodes the protein, ETS variant transcription factor 4. Notably, E1AF is known to play a role in keratinocyte differentiation and the regulation of transcription, among other functions. The ETV4 protein is 484 amino acid residues in length and 53.9 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 reported to be expressed in keratinocytes. This protein is known to be ubiquitinated, sumoylated and phosphorylated.
