Overview
This Recombinant Protein provides recombinant AP1B1 from Homo sapiens (Human), produced in E.coli (region 1-584aa). It is commonly used as a defined reagent for assay development, binding studies, and mechanistic research (RUO).
Key elements and design rationale
- Region: 1-584aa (domain boundaries can affect binding/activity readouts).
- Expression host: E.coli (may differ from native PTMs/processing).
- Tag(s): His, Myc (supports purification/detection; consider tag effects in controls).
Biological background
Also reported as Adaptor protein complex AP-1 subunit beta-1 (Adaptor-related protein complex 1 subunit beta-1) (Beta-1-adaptin) (Beta-adaptin 1) (Clathrin assembly protein complex 1 beta large chain) (Golgi adaptor HA1/AP1 adaptin beta subunit) (ADTB1) (BAM22) (CLAPB2). 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.
Research relevance and current trends
- Use of recombinant standards to improve assay calibration and cross-study comparability.

Common research applications
- Standard curve or spike-in reference for quantitative assays involving AP1B1
- Binding and specificity benchmarking for detection reagents (conceptual)
Notes for experimental interpretation
- Recombinant constructs may not capture all native isoforms or PTMs.
- Consider tag- or host-related effects when interpreting binding or activity.
- Use appropriate blanks and matrix/control concepts to separate signal from background.
