When people say that something really gets my goat,â they mean that they are extremely irritated. A wide variety of things could contribute to irritation, ranging from someone else's actions to a series of events, but, despite the turn of phrase, goats are not usually involved.
The major activator of Rho family GTPase is GPCR (G-Protein coupled Receptor). GPCRs that activate Rho and use G-Alpha12 or G-Alpha13 for signal transduction include receptors for LPA (Lysophosphatidic Acid) and S-1P (Sphingosine 1-Phosphate) and certain Hormones. Besides GPCR, Itgs (Integrins) also activate Rho GTPase.
Gene Family: Proprotein convertase subtilisin/kexin family (PCSK) Proprotein convertases: Proprotein convertases are a family of proteins that activate other proteins. Many proteins are inactive when they are first synthesized, because they contain chains of amino acids that block their activity. Proprotein convertases remove those chains and activate the protein. The prototypical proprotein convertase is furin.
