Genes affected

BCAS3 (HGNC:14347): (BCAS3 microtubule associated cell migration factor) Enables several functions, including acetyltransferase activator activity; beta-tubulin binding activity; and histone acetyltransferase binding activity. Involved in cellular response to estrogen stimulus; positive regulation of catalytic activity; and positive regulation of transcription by RNA polymerase II. Located in nucleus; phagophore assembly site; and transcriptionally active chromatin. Biomarker of breast cancer. [provided by Alliance of Genome Resources, Apr 2022]
