Vsx1 Gene Summary [Mouse]
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. Human ortholog(s) of this gene implicated in corneal dystrophy; keratoconus; and posterior polymorphous corneal dystrophy 1. Orthologous to human VSX1 (visual system homeobox 1).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Vsx1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- RNA polymerase II transcription factor activity, sequence-specific DNA binding
- transcription regulator
- double-stranded DNA binding
- nuclear localization sequence
- protein binding
