Provided below are ELISA kits targeting biogenesis of lysosomal organelles complex 1 subunit 1, a human protein encoded by BLOC1S1. This protein is 153 amino acids long, with a mass of 17.3 kDa, and is a member of the BLOC1S1 family. 2 isoforms have been identified. This is reported to be a cytoplasmic and mitochondrial protein. Other alias names for this protein include: BLOC-1 subunit 1, GCN5 (general control of amino-acid synthesis yeast homolog)-like 1, GCN5 general control of amino-acid synthesis 5-like 1, MTA1-interacting coactivator, and BLOS1.
