Gene: PITX2 (paired like homeodomain 2) Homo sapiens
Symbol: PITX2
Name: paired like homeodomain 2
Description: Exhibits several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; protein homodimerization activity; and transcription factor binding activity. Involved in animal organ development and regulation of transcription by RNA polymerase II. Localizes to the nucleoplasm and transcription factor complex. Implicated in Arts syndrome; Axenfeld-Rieger syndrome; and Axenfeld-Rieger syndrome type 1.
Type: protein-coding
RefSeq Status: REVIEWED
