basic FUNCTION
  • activating the phosphatidylinositol cycle
  • regulator of cell progression through retinoblastoma hyperphosphorylation and activation of both CCDN1/CDK4 and CCNE1/CDK2
  • potential convergent regulatory role of HTR2B and HTR2A receptors on the central respiratory network
  • neuromodulator that plays many different roles in adult and embryonic life
  • possible involvement in the generation of apoptotic events associated with cardiac remodelling during increased adrenergic stimulation
  • modulates, in a cell-autonomous manner, postmigratory skeletogenic cranial neural crest cell (NCC) behavior without altering early steps of cranial NCC development and migration
  • role in craniofacial development, contributing to our understanding of the interactive network of patterning signals that is involved in the development and evolution of the vertebrate mandibular arch
  • HTR2B, HTR2C receptors on motoneurons become constitutively active after injury and ultimately contribute to recovery of motoneuron function and emergence of spasms
  • role for HTR2B in impulsivity and in behaviour

  • significant association between the HTR2B Q20* variant with disorders characterized by impulsivity and impairment in working memory, a neurocognitive process contributing or predictive of executive cognitive function
