Predicted to enable macrophage colony-stimulating factor receptor binding activity; phosphotyrosine residue binding activity; and transmembrane receptor protein tyrosine kinase adaptor activity. Predicted to be involved in several processes, including negative regulation of macrophage migration; positive regulation of cellular component organization; and regulation of phosphorylation. Predicted to act upstream of or within response to bacterium. Predicted to be located in mitochondrion and nucleoplasm. Predicted to be part of protein-containing complex. Orthologous to human STAP1 (signal transducing adaptor family member 1). [provided by Alliance of Genome Resources, Apr 2022]
