Disease relevance of Stx1a

 

High impact information on Stx1a

  • Microinjection studies suggest that the nervous system-specific syntaxin 1A is important for calcium-regulated secretion from neuro-endocrine PC12 cells [5].
  • Three-dimensional structure of the neuronal-Sec1-syntaxin 1a complex [6].
  • The structure also indicates mechanisms that might couple the action of upstream effector proteins to conformational changes in syntaxin 1a and nSec1 that lead to core complex formation and membrane fusion [6].
  • During neuronal exocytosis, the vesicle-bound soluble NSF attachment protein (SNAP) receptor (SNARE) synaptobrevin 2 forms complexes with the plasma membrane-bound SNAREs syntaxin 1A and SNAP25 to initiate the fusion reaction [7].
  • Alteration of the kinetic properties of voltage-gated Ca(2+) channels, Ca(v)1.2 (Lc-type), Ca(v)2.2 (N type), and Ca(v)2.3 (R type), by syntaxin 1A (Syn1A) and synaptotagmin could modulate exocytosis [8].
 

Chemical compound and disease context of Stx1a

  • 4. In conscious rats previously exposed to 15 days hypoxia and studied under 10% O2, DMPPO (0.01, 0.05 and 0.1 mg kg(-1), i.v. bolus) caused a dose-dependent decrease in pulmonary arterial pressure (Pap) with no change in systemic artery pressure (Sap) and cardiac output [9].
