Receptor for a C-C type chemokine. Binds to MIP-1-alpha, RANTES, MCP-3 and, less efficiently, to MIP-1-beta or MCP-1 and subsequently transduces a signal by increasing the intracellular calcium ions level. Responsible for affecting stem cell proliferation (By similarity). Interacts with CREB3. Belongs to the G-protein coupled receptor 1 family.
