Enables connexin binding activity. Predicted to be involved in positive regulation of Golgi to plasma membrane protein transport. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be part of protein-containing complex. Predicted to be active in plasma membrane; trans-Golgi network; and transport vesicle. Orthologous to human CNST (consortin, connexin sorting protein). [provided by Alliance of Genome Resources, Apr 2022]
