High impact information on Tspyl2

  • This study suggests that reduction of the CINAP protein level by synaptic stimulation contributes to regulation of the transcriptional activity of the Tbr-1/CASK/CINAP protein complex and thus modifies expression of the NR2b gene [1].
  • Moreover, NMDA stimulation results in a reduction in the level of CINAP protein, via a proteasomal degradation pathway, correlating with a decrease in NR2b expression in neurons [1].
  • CASK interacting nucleosome assembly protein (CINAP) modulates gene expression and its abundance in cultured neurons is regulated by synaptic activity [2].
  • CINAP was widely expressed in different regions of adult mouse brain, including the cerebral cortex, hippocampus, striatum, hypothalamus, cerebellum, and two adult brain regions known to generate progenitor neurons [2].
  • Since the hypothalamus responds to several physiological responses, we examined whether CINAP protein levels in the paraventricular nucleus (PVN) of the hypothalamus are regulated by changes in osmolality achieved through oral administration of hypertonic saline [2].

Anatomical context of Tspyl2

  • During early development, CINAP was also expressed in regions where neuronal progenitor cells were actively dividing, the ventricular and subventricular zones, suggesting that in addition to regulating gene expression in mature neurons, CINAP may also play a role in dividing cells [2].
