SP3 ELISA kits are immunoassay tools for the measurement of the protein Sp3 transcription factor, which is encoded by the SP3 gene in humans. Functionally, this protein is reported to be a transcriptional factor that can act as an activator or repressor depending on isoform and/or post-translational modifications. The canonical protein structure is reported to have an amino acid length of 781 residues, a mass of 81.9 kDa, and is a member of the Sp1 C2H2-type zinc-finger protein family. It is known to be localized in the nucleus and is ubiquitously expressed across many tissue types. The protein has been noted to be post-translationally sumoylated and acetylated. Other alias names for this target include transcription factor Sp3, GC-binding transcription factor Sp3, specificity protein 3, and SPR2.
