Its actions are mediated by specific oxytocin receptors. These chemical can bind to receptors for other hormonally mediated processes. GPCR regulation is additionally mediated by gene transcription factors. These pathways are mediated principally by CYP3A4 and CYP3A5. Both are mediated via G protein activation. CD16a signaling is mediated by phosphorylation of Syk (pSyk). T cells is mediated by CD40 signalling. In yeast, this reduction is mediated by the sulfate assimilation pathway. This is mediated through MRP-1 dependent efflux. Instead those mechanisms are mediated by hemocytes. This process is mediated by the weak interaction. Transport is mediated by ATP binding cassette transporters. Biosynthesis is mediated by terpene synthase. Environmental pressures are thus mediated through social relations. In a gas, thermal conduction is mediated by discrete molecular collisions.
