Genes affected

ATP5F1B (HGNC:830): (ATP synthase F1 subunit beta) This gene encodes a subunit of mitochondrial ATP synthase. Mitochondrial ATP synthase catalyzes ATP synthesis, utilizing an electrochemical gradient of protons across the inner membrane during oxidative phosphorylation. ATP synthase is composed of two linked multi-subunit complexes: the soluble catalytic core, F1, and the membrane-spanning component, Fo, comprising the proton channel. The catalytic portion of mitochondrial ATP synthase consists of 5 different subunits (alpha, beta, gamma, delta, and epsilon) assembled with a stoichiometry of 3 alpha, 3 beta, and a single representative of the other 3. The proton channel consists of three main subunits (a, b, c). This gene encodes the beta subunit of the catalytic core. [provided by RefSeq, Jul 2008]

BAZ2A (HGNC:962): (bromodomain adjacent to zinc finger domain 2A) Enables histone binding activity. Contributes to RNA polymerase I core promoter sequence-specific DNA binding activity. Predicted to be involved in DNA methylation; histone deacetylation; and negative regulation of macromolecule metabolic process. Predicted to act upstream of or within chromatin organization and histone modification. Located in cytosol and nuclear speck. [provided by Alliance of Genome Resources, Apr 2022]
