AP-1 complex subunit sigma-3 (AP1S3), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-104aa. Protein Length: Full Length of Isoform 3. Tag Info: N-terminal GST-tagged. Target Protein Sequence: MIHFILLFSR QGKLRLQKWY ITLPDKERKK ITREIVQIIL SRGHRTSSFV DWKELKLVYK RYASLYFCCA IENQDNELLT LEIVHRYVEL LDKYFGNTWP FARA. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Subunit of clathrin-associated adaptor protein complex 1 that plays a role in protein sorting in the late-Golgi/trans-Golgi network (TGN) and/or endosomes. The AP complexes mediate both the recruitment of clathrin to mbranes and the recognition of sorting signals within the cytosolic tails of transmbrane cargo molecules. Involved in TLR3 trafficking . Reference: AP1S3 mutations are associated with pustular psoriasis and impaired Toll-like receptor 3 trafficking.Setta-Kaffetzi N., Simpson M.A., Navarini A.A., Patel V.M., Lu H.C., Allen M.H., Duckworth M., Bachelez H., Burden A.D., Choon S.E., Griffiths C.E., Kirby B., Kolios A., Seyger M.M., Prins C., Smahi A., Trembath R.C., Fraternali F. , Smith C.H., Barker J.N., Capon F.Am.
