SCAF4 ELISA kits are immunoassay tools for the measurement of the protein SR-related CTD associated factor 4, which is encoded by the SCAF4 gene in humans. Functionally, this protein is known to be an anti-terminator protein required to prevent early mRNA termination during transcription. The canonical protein structure is reported to have an amino acid sequence of 1147 residues and a mass of 125.9 kDa. It is known to be localized in the nucleus. As many as 3 protein isoforms have been reported. Other alias names for this target include CTD-binding SR-like protein rA4, SR-like CTD-associated factor 4, pre-mRNA splicing SR protein rA4, splicing factor serine alanine 15, and SR-related and CTD-associated factor 4.
