Ready-to-use ELISA kits are available for the detection of MACF, an alias of the protein, microtubule actin crosslinking factor 1. The official gene symbol is MACF1. The protein, with a mass of 838.3 kDa and length of 7388 residues, is reported to be cytoplasmic and membrane-associated. It is a member of the Plakin or cytolinker family and may be known by other names, including: ACF7, ABP620, macrophin 1 isoform, actin cross-linking family protein 7, 620 kDa actin binding protein, and microtubule-actin cross-linking factor 1, and MACF.
