S1H
Cat. No. CY-010
Structure:
Ac-Tyr-Ile-Pro-Lys-Glu-Gln-Lys-Tyr-Ser-Phe-Leu-Gln-Asn-Pro-Gln-Thr-NH2
Other Names:
S1H (36-51)
Activity:
Human growth hormone receptor antagonist
S1H is a 16-residue peptide designed as a direct sequence mimetic of the site 1 mini-helix (residues 36-51) of wild-type human growth hormone (hGH). S1H acts as an inhibitor by blocking the interaction of hGH with the human growth hormone receptor (hGHR). S1H mitigates phosphorylation of STAT5 in cells co-treated with hGH, reducing intracellular STAT5 phosphorylation levels to those of untreated controls. S1H
can be used as a chemical tool to study the molecular
nature of hGH–hGHR interactions.
