Summary: Predicted to enable transcription cis-regulatory region binding activity. Acts upstream of or within neuron maturation; retinal bipolar neuron differentiation; and visual perception. Located in nucleus. Is expressed in several structures, including 1st branchial arch; eye; genitourinary system; hemolymphoid system; and lung.

Vsx1 and Chx10 paralogs sequentially secure V2 interneuron identity during spinal cord development.
Title: Vsx1 and Chx10 paralogs sequentially secure V2 interneuron identity during spinal cord development.
Our results indicate that although VSX1 sequence variants can alter transcriptional activity, in the context of a mouse genetic model, at least one of these changes does not lead to corneal abnormalities. While we cannot exclude a role for VSX1 as a risk factor for corneal disease, on its own, it does not appear to play a major causative role.
Title: Investigating the Pathogenicity of VSX1 Missense Mutations and Their Association With Corneal Disease.
These findings reveal a role for Vsx1 in type 3a bipolar cells and suggest that Vsx1 function is required transiently in this cell type during the postnatal period.
Title: Requirement for the paired-like homeodomain transcription factor VSX1 in type 3a mouse retinal bipolar cell terminal differentiation.
findings indicate that Vsx1 regulates terminal gene expression in Type 7 bipolar cells and is necessary for proper ON visual signaling within a directionally selective circuit.
Title: Vsx1 regulates terminal differentiation of type 7 ON bipolar cells.
Although Vsx1 mRNA is upregulated in Chx10/Vsx2 deficient RPCs, Vsx1 does not genetically compensate for loss of Chx10/Vsx2, demonstrating that Prd-L:CVC genes, although important, are not absolutely required to initiate retinal development.

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.
