ID:HACD2_HUMAN DESCRIPTION: RecName: Full=Very-long-chain (3R)-3-hydroxyacyl-[acyl-carrier protein] dehydratase 2; EC=4.2.1.134; AltName: Full=3-hydroxyacyl-CoA dehydratase 2; Short=HACD2; AltName: Full=Protein-tyrosine phosphatase-like member B; FUNCTION: Responsible for the dehydration step in very long-chain fatty acids (VLCFAs) synthesis. CATALYTIC ACTIVITY: A very-long-chain (3R)-3-hydroxyacyl-[acyl- carrier protein] = a very-long-chain trans-2,3-dehydroacyl-[acyl- carrier protein] + H(2)O. SUBUNIT: Interacts with the condensation enzymes of the ELOVL family. Interacts with BCAP31. INTERACTION: P51572:BCAP31; NbExp=4; IntAct=EBI-530257, EBI-77683; SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: Highly expressed in testis, spleen, prostate, colon and heart, followed by moderate expression in thymus, ovary, small intestine, peripheral blood leukocytes, liver, skeletal muscle and pancreas. Weakly detected in kidney, placenta, brain and lung. MISCELLANEOUS: Turns over rapidly through degradation by the proteasome system. SIMILARITY: Belongs to the very long-chain fatty acids dehydratase HACD family. CAUTION: Shares some similarity with tyrosine phosphatase proteins but it has probably no phosphatase activity.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
