Overview
This Recombinant Protein provides recombinant OPTN from Homo sapiens (Human), produced in E.coli (region 1-577aa). It is commonly used as a defined reagent for assay development, binding studies, and mechanistic research (RUO).
Key elements and design rationale
- Region: 1-577aa (domain boundaries can affect binding/activity readouts).
- Expression host: E.coli (may differ from native PTMs/processing).
- Tag(s): His (supports purification/detection; consider tag effects in controls).
Biological background
Also reported as E3-14.7K-interacting protein (FIP-2) (Huntingtin yeast partner L) (Huntingtin-interacting protein 7) (HIP-7) (Huntingtin-interacting protein L) (NEMO-related protein) (Optic neuropathy-inducing protein) (Transcription factor IIIA-interacting protein) (TFIIIA-IntP). Plays an important role in the maintenance of the Golgi complex, in membrane trafficking, in exocytosis, through its interaction with myosin VI and Rab8.
Research relevance and current trends
- Quantitative mapping of ligand/receptor signaling to downstream phospho- and transcriptional programs.
- Use of recombinant standards to improve assay calibration and cross-study comparability.
Plays an important role in the maintenance of the Golgi complex, in membrane trafficking, in exocytosis, through its interaction with myosin VI and Rab8. Links myosin VI to the Golgi complex and plays an important role in Golgi ribbon formation. Negatively regulates the induction of IFNB in response to RNA virus infection. Plays a neuroprotective role in the eye and optic nerve. Probably part of the TNF-alpha signaling pathway that can shift the equilibrium toward induction of cell death. May act by regulating membrane trafficking and cellular morphogenesis via a complex that contains Rab8 and hungtingtin (HD). Mediates the interaction of Rab8 with the probable GTPase-activating protein TBC1D17 during Rab8-mediated endocytic trafficking, such as of transferrin receptor (TFRC/TfR); regulates Rab8 recruitnment to tubules emanating from the endocytic recycling compartment. Autophagy receptor that interacts directly with both the cargo to become degraded and an autophagy modifier of the MAP1 LC3 family; targets ubiquitin-coated bacteria (xenophagy), such as Cytoplasmic domain Salmonella enterica, and appears to function in the same pathway as SQSTM1 and CALCOCO2/NDP52. May constitute a cellular target for adenovirus E3 14.7, an inhibitor of TNF-alpha functions, thereby affecting cell death.
Common research applications
- Standard curve or spike-in reference for quantitative assays involving OPTN
- Binding interaction studies (e.g., SPR/BLI or plate-based binding formats)
- Cell-based stimulation studies with downstream marker readouts (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.
