GNG11 (G Protein Subunit Gamma 11): GNG11 (G Protein Subunit Gamma 11) is a gamma subunit of heterotrimeric G proteins, which are crucial components in intracellular signalling pathways activated by G protein-coupled receptors (GPCRs). GNG11 assists in modulating signal transduction across cell membranes, affecting various physiological processes such as sensory perception, immune response, and cell growth. Its role is vital for transmitting signals from outside the cell to the inside, enabling appropriate cellular responses.
