Anti-BAALC binder of MAP3K1 and KLF4 antibodies are used for the immunodetection of the protein encoded by the BAALC gene. In humans, the canonical protein has a reported length of 145 amino acid residues and a mass of 15.6 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 6 different isoforms for this protein. It is reported to be highly expressed in the neuroectoderm-derived tissues. It is believed to play a synaptic role at the postsynaptic lipid rafts possibly through interaction with CAMK2A. Post-translational modifications have been described, including palmitoylation and myristoylation. Other names for this target antigen include BAALC, MAP3K1 and KLF4 binding, BAALC, MEKK1 and KLF4 binding, brain and acute leukemia, cytoplasmic, and brain and acute leukemia cytoplasmic protein. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
