Protein CDV3 homolog also known as carnitine deficiency-associated gene expressed in ventricle 3 is a protein that in humans is encoded by the CDV3 gene.
CDV3 is a biomarker for hepatocellular carcinoma.[4] CDV3 has been considered as a potential target for gene therapy. Related gene families include plasma proteins and predicted intracellular proteins.[5]
Gene
Aliases
The CDV3 protein is also commonly known as tyrosine-phosphorylated protein 36 (TPP36). TPP36 isoforms have been found to be substrates of Abl tyrosine kinase.[6]
Locus
The CDV3 gene is on chromosome 3 (3q22.1).

Expression patterns
CDV3 is ubiquitously expressed, and at relatively high levels, in all tissues examined in the humans. Higher expression existed in certain diseases.
Gene profile
Various experiments showing expression of CDV3 demonstrated different patterns of tissue expression; however, it is concluded that the gene is expressed ubiquitously throughout all tissue types with more expression within tissues involved in the immune system and skeletal muscle tissue.[7]

The expression of CDV3 generally decreases throughout fetal development, but expression levels remain high.

Clinical significance
As earlier in the article, CDV3 has been found to be expressed in patients with various cancers and HIV. CDV3 has also been found to interact with Pr55 in the HIV retrovirus. Without further testing in expression, it is hard to determine how levels alter depending on disease state or the role this gene plays in these illnesses.
