Anti-Biogenesis of lysosome-related organelles complex 1, subunit 4 antibodies are used in antigen-specific immunodetection in biological samples. The target Biogenesis of lysosome-related organelles complex 1, subunit 4 is a known alias name of the protein biogenesis of lysosomal organelles complex 1 subunit 4, encoded by the BLOC1S4 gene in humans. This 217-amino acid residue protein is a known component of the BLOC-1 complex, a complex that is required for normal biogenesis of lysosome-related organelles (LRO), such as platelet dense granules and melanosomes. It is localized to the cytoplasm of the cell. It is reported to be widely expressed in many tissue types.
