The interaction between basic
octapeptide SPKKSPKK of Histone H1 and the alternating copolymer poly(dA-dT)-poly(dA-dT) results in [PSI]-type condensation [59].
The
octapeptide repeat region was not required for myelin maintenance, whereas mice PrP lacking central domain (aa 94-134) developed CDP.
Ethanol diet increases the sensitivity of rats to pancreatitis induced by cholecystokinin
octapeptide. Gastroenterology 117(3): 706-716, 1999.
C-terminal
octapeptide of cholecystokinin decreases food intake in man.
The 2 most widely used automated CTX assays recognize an
octapeptide epitope of the [[alpha].sub.1]-chain telopeptide, which contains a lysine residue that forms crosslinks.
ADH is an
octapeptide synthesized in the supraoptic nuclei of the hypothalamus and then stored and released from the posterior pituitary gland.
Distinction among the different Pax genes is dependent on the presence or absence of
octapeptide coding regions and a paired type homeobox [1].

E: exon of pax5; PD: paired box domain; OP:
octapeptide domain; HD: homeodomain; TA: transactivation domain; ID: inhibitory domain; WT: wild-type clone; MUT: mutation clone.

Angiotensin 1 circulates in the blood until its C-terminal dipeptide residue is cleaved by ACE to form an
octapeptide angiotensin 11, which acts as a potent vasoconstrictor (Udenigwe and Mohan, 2014).
Analysis showed that when the cell-penetrating peptide called R8 - an
octapeptide made from eight arginine amino acids - was attached to the nanoparticles, they were taken up by cells within five hours and had no toxic or inflammatory effect on the cells even after three days.
