Description: Sorting of integral membrane proteins at various stages of the endocytic and secretory pathways is mediated by vesicular trafficking between a variety of organelles. Two sorting signals are tyrosine-based and dileucine-based signals that interact with heterotetrameric adaptor protein complexes (AP-1, AP-2, AP-3, and AP-4), which are associated with the vesicle coats. These coatomers contain two large Adaptin proteins (alpha, gamma, delta, or epsilon and beta1, beta2, beta3, or beta4, respectively) that are noncovalently linked to one medium chain (µ1, µ2, µ3, or µ4) and one small chain (sigma1, sigma2, sigma3, or sigma4). The AP-1 and AP-3 complexes are involved in protein sorting from the TGN and endosomes, while AP-2 adaptor complexes are involved in clathrin-mediated endocytosis. In the AP-2 complex, Adaptin alpha is expressed in two very similar isoforms from two different genes. Adaptin alpha [A] (112kDa) is expressed primarily in brain, while Adaptin alpha [C] (105kDa) is expressed in brain, liver and other tissues. This antibody is routinely tested by western blot analysis.

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
