NHERF4 ELISA kits are immunoassay tools for the measurement of the protein NHERF family PDZ scaffold protein 4, which is encoded by the NHERF4 gene in humans. Functionally, this protein is known to act as a regulatory protein that associates with GUCY2C and negatively modulates its heat-stable enterotoxin-mediated activation. The canonical protein structure is reported to have an amino acid sequence of 571 residues and a mass of 61 kDa. It is known to be localized in the cell membrane and cytoplasm and is reported to be expressed in kidney and the gastrointestinal tract. As many as 5 protein isoforms have been reported. The protein has been noted to be post-translationally phosphorylated. Other alias names for this target include Na(+)/H(+) exchange regulatory cofactor 4, PDZ domain containing 3, PDZ domain-containing protein 2, PDZ domain-containing protein 3, and Na(+)/H(+) exchange regulatory cofactor NHE-RF4.
