Webincrease in the activation of the Nodal-ACVRIIA sig- nalling pathway. The high level of phosphoinositide and Ca 2 + signalling on the ventral side is driven by Wnt5A/11, which acts by stimulating PLC (phospholipase C) to produce the two second messengers InsP 3 and diacylglycerol (DAG). Phospholipase C (PLC) is a class of membrane-associated enzymes that cleave phospholipids just before the phosphate group (see figure). It is most commonly taken to be synonymous with the human forms of this enzyme, which play an important role in eukaryotic cell physiology, in particular signal … See more Mammalian variants The extensive number of functions exerted by the PLC reaction requires that it be strictly regulated and able to respond to multiple extra- and intracellular inputs with appropriate … See more Activation Receptors that activate this pathway are mainly G protein-coupled receptors coupled to the Gαq subunit, including: • See more PLC cleaves the phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) into diacyl glycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). Thus PLC has a profound impact on … See more In mammals, PLCs share a conserved core structure and differ in other domains specific for each family. The core enzyme includes a split triosephosphate isomerase (TIM) barrel See more The primary catalyzed reaction of PLC occurs on an insoluble substrate at a lipid-water interface.
