AP1S1 Antibody (N-Term)

Peptide Affinity Purified Rabbit Polyclonal Antibody (Pab)

  • WB - AP1S1 Antibody (N-Term) AP5009a
    Western blot analysis of AP1S1 Antibody (N-Term)(Cat. #AP5009a) in MDA-MB231 cell line lysates (35ug/lane).AP1S1 (arrow) was detected using the purified Pab.
  • IHC-P - AP1S1 Antibody (N-Term) AP5009a
    AP1S1 Antibody (N-Term) (Cat. #AP5009a) immunohistochemistry analysis in formalin fixed and paraffin embedded human skeletal muscle followed by peroxidase conjugation of the secondary antibody and DAB staining. This data demonstrates the use of the AP1S1 Antibody (N-Term) for immunohistochemistry. Clinical relevance has not been evaluated.
  • FC - AP1S1 Antibody (N-Term) AP5009a
    AP1S1 Antibody (N-Term) (Cat. #AP5009a) flow cytometric analysis of MDA-MB231 cells (right histogram) compared to a negative control cell (left histogram).FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.

Protein Information
Name AP1S1
Synonyms AP19, CLAPS1
Function 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 membranes and the recognition of sorting signals within the cytosolic tails of transmembrane cargo molecules.
Cellular Location Golgi apparatus. Cytoplasmic vesicle membrane; Peripheral membrane protein; Cytoplasmic side. Membrane, clathrin-coated pit. Note=Component of the coat surrounding the cytoplasmic face of coated vesicles located at the Golgi complex
Tissue Location Widely expressed.

AP1S1 is part of the clathrin coat assembly complex which links clathrin to receptors in coated vesicles. These vesicles are involved in endocytosis and Golgi processing. This protein, as well as beta-prime-adaptin, gamma-adaptin, and the medium (mu) chain AP47, form the AP-1 assembly protein complex located at the Golgi vesicle.
