Anti-MARCKS like 1 antibodies are used in the immunodetection of the protein encoded by the MARCKSL1 gene. In humans, the canonical protein has a reported length of 195 amino acid residues and a mass of 19.5 kDa. Its subcellular localization is in the cell membrane and cytoplasm. A member of the MARCKS protein family, it is known to be involved with cell proliferation and nervous system development. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include MARCKS-like protein 1, mac-MARCKS, macrophage myristoylated alanine-rich C kinase substrate, and MARCKS-related protein.
