Genes affected

BSX (HGNC:20450): (brain specific homeobox) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including eating behavior; mammary gland involution; and positive regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm. Predicted to be part of chromatin. [provided by Alliance of Genome Resources, Apr 2022]
