Gene: Pitx2 (paired-like homeodomain 2) Rattus norvegicus
Symbol: Pitx2
Name: paired-like homeodomain 2
Description: Exhibits DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including animal organ development; positive regulation of transcription by RNA polymerase II; and response to vitamin A. Localizes to nucleus. Biomarker of autosomal dominant polycystic kidney disease and hypothyroidism. Human ortholog(s) of this gene implicated in Arts syndrome; Axenfeld-Rieger syndrome; Axenfeld-Rieger syndrome type 1; anterior segment dysgenesis 4; and ring dermoid of cornea. Orthologous to human PITX2 (paired like homeodomain 2); PARTICIPATES IN transforming growth factor-beta superfamily mediated signaling pathway; INTERACTS WITH 1,3-dinitrobenzene; acrylamide; all-trans-retinoic acid.
Type: protein-coding
RefSeq Status: VALIDATED
