Summary: Enables DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including camera-type eye morphogenesis; circulatory system development; and positive regulation of cell differentiation. Acts upstream of or within several processes, including epithelial cell differentiation; hepatocyte cell migration; and regulation of transcription by RNA polymerase II. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; brain; cardiovascular system; sensory organ; and skin. Used to study dilated cardiomyopathy and obesity. Orthologous to human PROX1 (prospero homeobox 1). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
