BTBD9
BTB domain containing 9 is a protein that in humans is encoded by the BTBD9 gene.
BTBD9 is in a subgroup of BTB(POZ) proteins, which contribute to the forming of limbs and determination of cell fate in developing Drosophila melanogaster. BTB(POZ) proteins also play a role in cellular functions such as: cytoskeleton regulation, transcription regulation, the gating and assembly of ion channels, and ubiquitination of proteins. BTBD9 is highly expressed throughout the brain and shows variable levels of expression in most other body tissues.
The gene is located on the short arm of chromosome 6 and the domain contains eight exons and seven introns. The chromosome 6 locational domain that codes for BTB(POZ) proteins is understood to contain genes encoding protein-protein interactions. BTBD9 is a protein located in cellular cytosol and also expressed within Human embryonic kidney cell lineages. There is also evidence suggesting that BTBD9 is highly expressed within the human nervous system from comparison analysis to Drosophila and human cell studies.
