SUPT4H1 ELISA kits are immunoassay tools for the measurement of the protein SPT4 homolog, DSIF elongation factor subunit, which is encoded by the SUPT4H1 gene in humans. Functionally, this protein is a known component of the DRB sensitivity-inducing factor complex (DSIF complex), which regulates mRNA processing and transcription elongation by RNA polymerase II. The canonical protein structure is reported to have an amino acid length of 117 residues, a mass of 13.2 kDa, and is a member of the SPT4 protein family. It is known to be localized in the nucleus and is widely expressed across many tissue types. Other alias names for this target include SPT4H, SUPT4H, Supt4a, transcription elongation factor SPT4, DRB sensitivity-inducing factor 14 kDa subunit, and SPT4.
