2D Structure
Description

Slaframine is a mycotoxin produced by the fungus Rizoctonia leguminicola. It is a parasympathomimetic compound and causes increased exocrine function, especially salivation. Along with swainsonine, the other biologially active compound of R. leguminicola, it is known to cause a condition called "slobbers syndrome" in livestock that has ingested contaminated feed.

Targets

General Function:
Phosphatidylinositol phospholipase c activity
Specific Function:
The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is Pi turnover.
Gene Name:
CHRM1
Uniprot ID:
P11229
Molecular Weight:
51420.375 Da
Mechanism of Action:
Slaframine is a parasympathomimetic compound and causes increased secretion by salivary glands, pancreas, and other exocrine and endocrine glands. This is due to its activity as a cholingergic agonist. Slaframine has a high affinity for muscarinic receptors, especially in the gastrointestinal tract, and it stimulates these to produce its parasympathomimetic effects.

General Function:
G-protein coupled acetylcholine receptor activity
Specific Function:
The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is adenylate cyclase inhibition. Signaling promotes phospholipase C activity, leading to the release of inositol trisphosphate (IP3); this then triggers calcium ion release into the cytosol.
