Listed are ELISA Kits for the detection of adaptor protein complex AP-1, sigma 1, an alias name of adaptor related protein complex 1 subunit sigma 1. The human protein, encoded by the gene AP1S1, is 158 amino acid residues long and has a mass of 18,733 daltons. However, there are up to 2 reported isoforms. It is a member of the Adaptor complexes small subunit family. The gene is associated with Mental retardation, enteropathy, deafness, peripheral neuropathy, ichthyosis, and keratoderma. This target may also be known as: HA1 19 kDa subunit, adapter-related protein complex 1 sigma-1A subunit, adaptor protein complex AP-1 subunit sigma-1A, adaptor-related protein complex 1 subunit sigma-1A, and clathrin assembly protein complex 1 sigma-1A small chain.
