G protein-coupled receptors (GPCRs), such as GPR34, are integral membrane proteins containing 7 putative transmembrane domains (TMs). These proteins mediate signals to the interior of the cell via activation of heterotrimeric G proteins that in turn activate various effector proteins, ultimately resulting in a physiologic response.[supplied by OMIM, Apr 2006]
Forensic Context
A systematic review of postmortem human brain studies found that the GPR34 mRNA, a microglial marker, shows increased transcription in the dorsolateral prefrontal cortex of individuals who died by suicide compared to controls [Yamamoto et al. DOI:10.3390/Ijms25115750].
