Uroguanylin: structure and activity of a second endogenous peptide that stimulates intestinal guanylate cyclase.

Hamra, F K, Forte, L R, Eber, S L, Pidhorodeckyj, N V, Krause, W J, Freeman, R H, ...

The intestinal hormone guanylin and bacterial heat-stable enterotoxins (STs) are members of a peptide family that activates intestinal membrane guanylate cyclase. Two different peptides that activate...

Guanylin: an endogenous activator of intestinal guanylate cyclase.

Currie, M G, Fok, K F, Kato, J, Moore, R J, Hamra, F K, Duffin, K L, ...

Intestinal guanylate cyclase mediates the action of the heat-stable enterotoxin to cause a decrease in intestinal fluid absorption and to increase chloride secretion, ultimately causing diarrhea. An...

Identity of a second type of allatostatin from cockroach brains: an octadecapeptide amide with a tyrosine-rich address sequence.

Pratt, G E, Farnsworth, D E, Fok, K F, Siegel, N R, McCormack, A L, Shabanowitz, J, ...

An octadecapeptide that inhibits juvenile hormone synthesis has been isolated by HPLC from brain-retrocerebral complexes of the cockroach Diploptera punctata. The primary structure of this...

Engineering of site-directed antisera against vertebrate calmodulin by using synthetic peptide immunogens containing an immunoreactive site.

Van Eldik, L J, Fok, K F, Erickson, B W, Watterson, D M

Site-directed antisera against vertebrate calmodulin were elicited in rabbits by injection of a synthetic immunogen containing the pentadecapeptide...

Guanylin stimulation of Cl- secretion in human intestinal T84 cells via cyclic guanosine monophosphate.

Forte, L R, Eber, S L, Turner, J T, Freeman, R H, Fok, K F, Currie, M G

Intestinal salt and fluid secretion is stimulated by Escherichia coli heat-stable enterotoxins (ST) through activation of a membrane guanylate cyclase found in the intestine. Guanylin is an...

Distribution of heat-stable enterotoxin/guanylin receptors in the intestinal tract of man and other mammals.

Krause, W J, Cullingford, G L, Freeman, R H, Eber, S L, Richardson, K C, Fok, K F, ...

The human intestinal tract, as well as that of several eutherian and metatherian mammals, was examined for the distribution of heat-stable enterotoxin (ST)/guanylin receptors. These receptors were...
