COMM_Domain containing protein 5, also called HCaRG (hypertension-related, calcium-regulated gene). HCaRG is a nuclear protein that might be involved in cell proliferation; it is negatively regulated by extracellular calcium concentration, and its basal mRNA levels are higher in hypertensive animals. The COMM Domain is found at the C-terminus of a variety of proteins; presumably all COMM_Domain containing proteins are located in the nucleus and the COMM domain plays a role in protein-protein interactions. Several family members have been shown to bind and inhibit NF-kappaB.
