Anti-Syntabulin antibodies are used in the immunodetection of the protein encoded by the SYBU gene. In humans, the canonical protein has a reported length of 663 amino acid residues and a mass of 72.4 kDa. Its subcellular localization is in the cytoplasmic vesicles and cytoplasm. Alternative splicing is reported to yield 5 different isoforms for this protein. It is reported to be part of a kinesin motor-adapter complex that is critical for the anterograde axonal transport of active zone components and contributes to activity-dependent presynaptic assembly during neuronal development. Other names for this target antigen include GOLSYN B protein, GOLSYN C protein, Golgi-localized protein, golgi-localized syntaphilin-related protein, implicated in syntaxin trafficking in neurons, and GOLSYN A protein.
