Molecular Function: This is what occurs at the molecular level. Examples of these are catalysis or transport [1] .
Cellular Component: This refers to the locations are organelles in which this takes gene is expressed in [1] .
Biological Processes: The bigger idea to what going on. Unlike molecular function which might just be catalysis, this might look at DNA Repair which involves catalysis [1] .
ABCD1 GO Terms
Molecular Function: ABCD1's is a transporter of fatty acids.
Biological Process: This is involved in beta oxidation and other peroxisomal biogenesis.
Cellular Component: ABCD1 is found in the membranes of the peroxisome.
Conclusion
The ABCD1 gene is responsible for making a transporter protein in the peroxisomal membrane. This protein allows the transports of fatty acids into the peroxisome. These fatty acids are then broken down via beta oxidation.
