Predicted to enable protein homodimerization activity. Predicted to be involved in several processes, including cellular response to lipopolysaccharide; defense response to other organism; and positive regulation of membrane permeability. Predicted to be located in intracellular membrane-bounded organelle and midbody. Predicted to be active in extracellular space. Orthologous to several human genes including DEFA3 (defensin alpha 3) and DEFA6 (defensin alpha 6). [provided by Alliance of Genome Resources, Apr 2022]
