PTPLAD2 (protein tyrosine phosphatase-like A domain containing 2), also known as HACD4 (3-hydroxyacyl-CoA dehydratase 4), is a 232 amino acid multi-pass membrane protein that belongs to the very long-chain fatty acids dehydratase HACD family. Localizing to endoplasmic reticulum membrane, the PTPLAD2 protein is responsible for the dehydration step in very long-chain fatty acids (VLCFAs) synthesis. Highly expressed in leukocytes, and low expression in heart, spleen, kidney and placenta, the PTPLAD2 protein interact with the condensation enzymes of the ELOVL family. The PTPLAD2 gene is conserved in chimpanzee, dog, cow, mouse, rat and chicken, and maps to human chromosome 9p21.3. Chromosome 9 consists of about 145 million bases and 4% of the human genome and encodes nearly 900 genes. Hereditary hemorrhagic telangiectasia, which is characterized by harmful vascular defects, is associated with the chromosome 9 gene encoding endoglin protein, ENG. |
