GPCR G2A is a G-protein linked receptor for lysophosphatidylcholine (LPC). It may play a role as a sensor of LPC levels at sites of inflammation to limit tissue-infiltrating-cells and progression to overt autoimmune disease and functions at the G2/M checkpoint to delay mitosis. It also may serve as a mechanism for T and B cells, and other cell types, to slow their proliferation and repair damaged DNA. It is highly expressed in macrophages and hematopoietic tissues rich in lymphocytes, like spleen and thymus, but weakly expressed in heart and lung. In atherosclerotic plaques, expression was observed around the lipid core and at the shoulder region. It is induced by DNA-damaging agents.
