  • Tissue specificity
    Strong expression in kidney and heart, and lower in liver and skeletal muscle.
  • Pathway
    Lipid metabolism; fatty acid beta-oxidation.
  • Involvement in disease
    Defects in CPT1A are the cause of carnitine palmitoyltransferase 1A deficiency (CPT1AD) [MIM:255120]; also known as CPT-I deficiency or CPT1A deficiency. CPT1AD is a rare autosomal recessive metabolic disorder of long-chain fatty acid oxidation characterized by severe episodes of hypoketotic hypoglycemia usually occurring after fasting or illness. Onset is in infancy or early childhood.
  • Sequence similarities
    Belongs to the carnitine/choline acetyltransferase family.
  • Cellular localization
    Mitochondrion outer membrane.

  • Overlay histogram showing HAP1 wildtype (green line) and HAP1-CPT1A  knockout cells (red line) stained with ab171449. The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab171449, 1µg/ml dilution) for 30 min at 22°C.

    A rabbit monoclonal IgG isotype control antibody  (ab199091) was used at the same concentration and conditions as the primary antibody (HAP1 wildtype - black line, HAP1-CPT1A    knockout - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity).

    Acquisition of >5,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter.

  • Flow cytometric analysis of HeLa cells (4% paraformaldehyde-fixed;  methanol-permeablized) labeling CPT1A with ab171449 at 5 µg/mL (green) compared with an isotype control ab170192 at 5 µg/mL (black).  Isotype control was labeled with a Goat Anti-mouse Alexa Fluor® 488 secondary antibody prior to signal measurement on the FL-1 channel.

  • Immunofluoresecence analysis of HeLa cells (4% paraformaldehyde-fixed, methanol-permeablized) labeling CPT1A with ab171449 at 5µg/ml overnight.  100x magnification.

    A) HeLa cells labeled with ab171449 at 5 µg/mL.
    B) HeLa cells labeled with Anti-HSP60 (1/3000, ab46798), Secondary antibody used was goat anti-rabbit Dylight-594 (1/1000, ab96897).
    C) Merged Image of A and B showing specificity of mitochondrial staining.
