Dab2 Antibody

About the Target

DAB2(Disabled-2) is a multifunctional adaptor protein that plays a critical role in clathrin-mediated endocytosis and the regulation of various signalling pathways such as MAPK, Wnt, and TGFβ. Structurally, DAB2 consists of 770 amino acids encoded by 15 exons on chromosome 5p13, and it includes a phosphotyrosine-binding (PTB) domain at the N-terminus and a proline-rich domain (PRD) at the C-terminus, which contains a myosin-interacting region. Depending on the literature source, DAB2 may also be discussed as Disabled homolog 2 and DOC2.

Reported cellular context includes coated pit, cytoplasm, cytoplasmic vesicle, and membrane, which can matter when signal is compared across treatments or changing cell states. Following DAB2 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

DAB2 is commonly interpreted in the context of cancer and cell signaling research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans coated pit, cytoplasm, and cytoplasmic vesicle, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• apparent redistribution between coated pit, cytoplasm, and cytoplasmic vesicle across matched conditions
• changes associated with proliferative state, oncogenic signaling, or treatment response
• signal-dependent shifts after ligand, inhibitor, or growth-factor perturbation
• co-patterning with orthogonal markers and control conditions that clarify pathway state

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for DAB2. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.

Standardize sampling time, control choice, and downstream analysis thresholds so apparent differences in DAB2 reflect biology rather than handling. When interpreting DAB2, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.

For multi-run studies, a shared reference condition can keep DAB2 trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.
