Target intelligence / Profile preview
ATP-binding cassette transporter subfamily A (ABCA)
- Target
- ABCA
- Molecular classification
- Transporter, ATP-binding cassette transporter, Membrane protein
01
Overview
The ATP-binding cassette transporter subfamily A consists of integral membrane proteins specialized primarily for lipid-related substrate export. Their activity is essential for normal physiological processes such as cholesterol homeostasis and vision. Dysfunctional variants cause diverse genetic diseases related to impaired molecular trafficking at cellular membranes.
02
Mechanism of action
Modulation of transport activity (substrate-specific)
03
Biological functions
Lipid transportCholesterol effluxPhospholipid transferSurfactant productionSkin barrier formationRetinoid transport
04
Disease associations
Tangier diseaseFamilial HDL deficiencyHarlequin ichthyosisStargardt diseaseLipid metabolism disordersNeurodegenerative disease
05
Safety considerations
Potential for off-target effects due to broad substrate specificityAltered lipid metabolismDrug-drug interactions affecting transport function
