HOPX (homeodomain only protein x) gene is mapped in human chromosome 4q12. Unlike HOX proteins, it lacks a DNA-binding domain that is required for protein-DNA interactions. HOPX is widely expressed, but not in malignant tissues including choriocarcinoma, lung, uterine endometrial and gastrointestinal cancers. The gene contains 3 transcript variants HOPX- a, ß, ? encoding the same protein.

Biochem Physiol Actions: HOPX (homeodomain only protein x) is involved in cardiac and skeletal muscle development by recruiting histone deacetylases. It controls the SRF (serum response factor)-dependent gene expression for the regulation of cardiac development. Downregulation of HOPX leads to cardiac hypertrophy in mice. In advanced human heart failure, HOPX expression is reduced. It acts as co-chaperone and organises the Hsp70-Hsp90 (heat shock proteins) proteins. It serves as a maker for a number of stem cell types. Studies show that HOPX inhibits tumour cell proliferation rate, migration and invasion in lung cancer. It also increase cell death by the activation of oncogenic Ras (GTPase) and the downstream MAPK (mitogen activated protein kinase) pathway.
