ATP-binding cassette sub-family A member 3 Antibody

About the Target

ATP-binding cassette sub-family A member 3 (ABCA3) is a highly conserved, multi-pass transmembrane glycoprotein in the ABC transporter superfamily that uses ATP hydrolysis to transport phospholipids into lamellar bodies (LBs) of alveolar type II cells, where pulmonary surfactant is assembled and stored. Structurally, ABCA3 consists of two similar halves, each containing six transmembrane domains and a cytosolic nucleotide-binding domain (NBD) with Walker A, Walker B, and ABCA-specific signature motifs, plus two essential N-linked glycosylation sites at Asn124 and Asn140 required for proper folding, stability, and LB targeting. Depending on the literature source, ABCA3 may also be discussed as ATP-binding cassette sub-family A member 3 and Phospholipid-transporting ATPase ABCA3.

Reported cellular context includes cytoplasmic vesicle, endosome, lysosome, and membrane, which can matter when signal is compared across treatments or changing cell states. Following ABCA3 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state. In practice, this target is often considered at the family or isoform-group level, so experimental interpretation benefits from matched controls and clear comparison logic.

Research Context

ABCA3 is commonly interpreted in the context of metabolism research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cytoplasmic vesicle, endosome, and lysosome, 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 cytoplasmic vesicle, endosome, and lysosome across matched conditions
• responses linked to nutrient status, mitochondrial state, or metabolic rewiring
• co-patterning with orthogonal markers and control conditions that clarify pathway state
• time-matched comparisons so changes reflect biology rather than handling or sampling drift

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for ABCA3. 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 ABCA3 reflect biology rather than handling. When interpreting ABCA3, 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 ABCA3 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.
