Octapeptide repeat region and N-terminal half of hydrophobic region of prion protein (PrP) mediates PrP-dependent activation of superoxide dismutase.
Condensation of DNA and chromatin by an SPKK-containing
octapeptide repeat motif present in the C-terminus of histone H1.
The resulting
octapeptide, angiotensin II (Ang II), binds to transmembrane receptors and initiates several signaling pathways, including initiating the release of aldosterone from the adrenal gland.
Within the enzyme cascade of the renin-angiotensin system, ACE removes histidyl-leucine from angiotensin I to form the physiologically active
octapeptide angiotensin II, one of the most potent vasoconstrictors known.
Angiotensin-converting enzyme converts the inactive decapeptide, angiotensine I to the active
octapeptide and potent vasoconstrictor angiotensin II, which is the main product of the renin-angiotensin system (RAS) [12].
Antinociceptive action of Cholecystokinin
octapeptide (CCK) and related peptides in rats and mice: effects of naloxone and peptidase inhibitors.
In the group of orally infected squirrel monkeys, 3 had a unique heterozygous genotype that encoded either 4 or 5
octapeptide repeats.
Syntocinon is the synthetic form of
octapeptide oxytocin.
However, antigens occur in countless shapes and forms as there are multiple ways to generate an
octapeptide (the length of peptide antigens held in the MHC binding groove).
The N-terminal domain is composed of five
octapeptide repeats that are rich in proline and glycine, the first of which is termed a "pseudorepeat" because it lacks histidine.
25, Boots Contains 'Inhibox' to freeze, tighten and smooth expression wrinkles, plus the wrinkle-relaxing
octapeptide 'Snap-8' to minimise any muscle movement.
Other peptides such as tripeptide and
octapeptide complement the effects of Argireline and Matrixyl to minimize fine lines, decrease wrinkle depths and provide overall smoother, younger looking skin.
