Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific; chromatin binding activity; and nucleic acid binding activity. Involved in negative regulation of photoreceptor cell differentiation; positive regulation of amacrine cell differentiation; and positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including negative regulation of oligodendrocyte differentiation; nervous system development; and skeletal system development. Located in nucleus. Is expressed in several structures, including branchial arch; embryo ectoderm; genitourinary system; sensory organ; and tooth. Orthologous to human DLX2 (distal-less homeobox 2).

Overexpression of Dlx2 enhances early chondrocyte differentiation by increasing accumulation of Col2alpha1, type II collagen and aggrecan, but interferes later stages of chondrocyte differentiation through inhibiting MMP13 expression.

Studies revealed that Dlx1/2 and Otp are required for the specification of growth hormone-releasing hormone (GHRH)- and AgRP-neurons, respectively. Dlx1/2 suppress agouti-related protein (AgRP)-neuronal fate by directly binding and repressing the Otp gene, uncovering a novel Dlx1/2-Otp gene regulatory axis critical for the segregation of GHRH- and AgRP-neuronal fates.

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.
