Gene Type: protein_coding_gene
Location: Chr: 20 Mapping Details/Browsers
Description: Exhibits gap junction hemi-channel activity and voltage-gated ion channel activity. Involved in cell-cell signaling. Localizes to connexin complex. Is expressed in several structures, including heart; kidney; liver; nervous system; and neural tube. Orthologous to human GJD2 (gap junction protein delta 2).
