Provided below are ELISA kits targeting microtubule actin crosslinking factor 1, a human protein encoded by MACF1. This protein is 7388 amino acids long, with a mass of 838.3 kDa, and is a member of the Plakin or cytolinker family. 5 isoforms have been identified. This is reported to be a cytoplasmic and membrane protein. There is a noted implication in Lissencephaly 9 with complex brainstem malformation. Other alias names for this protein include: microtubule-actin cross-linking factor 1, 620 kDa actin binding protein, actin cross-linking family protein 7, macrophin 1 isoform, ABP620, ACF7, and LIS9.
