Receptor for a C-C type chemokine. Binds to MIP-1-alpha, MIP-1-delta, RANTES, and 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. Interacts with CREB3. Widely expressed in different hematopoietic cells. Up-regulated by CREB3. Belongs to the G-protein coupled receptor 1 family.
