Enables biotin-[propionyl-CoA-carboxylase (ATP-hydrolyzing)] ligase activity and identical protein binding activity. Involved in response to biotin. Predicted to be located in chromatin; cytosol; and nuclear periphery. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in holocarboxylase synthetase deficiency. Orthologous to human HLCS (holocarboxylase synthetase). [provided by Alliance of Genome Resources, Apr 2022]
