Anti-Naglt1 antibodies enable researchers to detect and measure the Naglt1 antigen in biological samples. This target is a reported synonym of the MFSD4B gene, which encodes major facilitator superfamily domain containing 4B. This protein is known to function in the transport of ions, among other biological roles. The human version of Naglt1 has a canonical amino acid length of 518 residues and a protein mass of 56.2 kilodaltons. It is reported to be localized in the cell membrane of cells and widely expressed in many tissue types. Naglt1 is a member of the Major facilitator protein superfamily.
