  • Ciliary assembly/disassembly
  • Trafficking (BBSome, small GTPases, vesicular transport, ATPases)

Function

DAF-6/intraflagellar transport and the OCR-2/OSM-9 TRPV channel act in concert, regulating two layers of activation of tph-1 in the ADF neurons. The TRPV sig ling turns on tph-1 expression under favorable and aversive conditions, whereas i ctivation of DAF-6 by stress results in further upregulation of tph-1 independently of OCR-2/OSM-9 activity. tph-1 has expression in dendritic cilia of a pair of ADF serotonergic chemosensory neurons(19339602).

Model organism evidence

C. elegans (1 reference)

Mutants of daf-6 or intraflagellar transport constitutively upregulate tph-1 expression.
