Disease relevance of HTR4

 

Psychiatry related information on HTR4

 

High impact information on HTR4

  • These include ectopic receptors for gastric inhibitory polypeptide (GIP), beta-adrenergic agonists, or LH/hCG; a similar outcome can result from altered activity of eutopic receptors, such as those for vasopressin (V1-AVPR), serotonin (5-HT4), or possibly leptin [8].
  • The more recently identified 5-HT4 receptor almost undoubtedly represents a fourth 5-HT receptor class on the basis of operational and transductional data, but this will only be definitively shown when the cDNA for the receptor has been cloned and the amino acid sequence of the protein is known [9].
  • Serotonin inhibits Na+/H+ exchange activity via 5-HT4 receptors and activation of PKC alpha in human intestinal epithelial cells [10].
  • Studies using specific inhibitors and agonists showed that the effects of 5-HT were mediated by 5-HT4 receptors [10].
  • The effects of the 5-HT3 and 5-HT4 antagonists in guinea pig colon were additive [11].

Associations of HTR4 with chemical compounds

  • Neither uncoupling nor beta-arrestin/dynamin-dependent endocytosis required the serine and threonine residues localized within the specific C-terminal domains of the 5-HT4R splice variants [21].
  • Taken together, our results show an overexpression of the 5-HT4 receptor in cisapride-responsive AIMAH [1].
  • In these tissues, 5-HT4 receptor mRNA expression was 3 to 16 times higher than in normal glands, likely explaining the abnormal in vivo cortisol response to cisapride [1].
  • Moreover, we further identified a sequence within the C-terminal tail upstream of L358, rich in serine and threonine residues, that played a crucial role in maintaining 5-HT4R under its inactive conformation [22].
  • Hypomotility remains an attractive therapeutic target in IBS and the new generation of prokinetics includes several partial agonists at the 5-HT4 receptor, such as tegaserod (HTF-919) and prucalopride (R0-93877) [23].
 

Regulatory relationships of HTR4

 

Other interactions of HTR4

  • The T allele of the 83097 C>T polymorphism of HTR4 showed a tendency of preferential transmission to probands with ADHD (chi(2)=2.699, P=0.100) [17].
  • The preferential 5-HT1A receptor agonist 8-hydroxy-2-(di-n-propylamino)tetraline (up to 0.3 microM) and the selective 5-HT4 receptor agonist cisapride (up to 1 microM) failed to inhibit tritium overflow [25].
  • Serotonin receptors belonging to the 5-HT3 and 5-HT4 subtype are the most extensively studied in gastroenterology, although hitherto 'orphan' receptor subtypes, such as the 5-HT7 and the 5-HT(1B/D) receptors, are now emerging [23].
  • Both PHA stimulated human and monkey PBMCs express mRNAs for 5-HT1(A), 5-HT1(B), 5-HT1(E), 5-HT2(A), 5-HT3, 5-HT4, 5-HT6 receptor types/subtypes [26].
  • Computational model of the complex between GR113808 and the 5-HT4 receptor guided by site-directed mutagenesis and the crystal structure of rhodopsin [27].
