Anti-EFA6 antibodies enable researchers to detect and measure the EFA6 antigen in biological samples. This target is a reported synonym of the PSD gene, which encodes pleckstrin and Sec7 domain containing. This protein is known to function in neuronal development and signal transduction pathways, among other biological roles. The human version of EFA6 has a canonical amino acid length of 1024 residues and a protein mass of 109.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. EFA6 is a member of the PSD protein family.
