conejetin2

Conejetin2 is a protein that in humans is encoded by the CNJ2 gene. This gene is located on the long (q) arm of chromosome 1 at position 21.1. The CNJ2 gene is involved in the regulation of cone photoreceptor cell differentiation and function in the retina. Mutations in this gene have been associated with a form of cone-rod dystrophy, a group of inherited eye diseases that affect the photoreceptor cells in the retina.

The protein encoded by CNJ2 is a member of the cone-rod homeobox family of transcription factors. It plays a crucial role in the development and maintenance of cone photoreceptors, which are responsible for color vision. The CNJ2 protein binds to specific DNA sequences and regulates the expression of genes involved in cone photoreceptor differentiation and function.

Cone-rod dystrophy caused by CNJ2 mutations typically presents with symptoms such as night blindness, color vision defects, and progressive vision loss. The severity and progression of symptoms can vary among individuals. Currently, there is no specific treatment for cone-rod dystrophy caused by CNJ2 mutations, and management focuses on symptom relief and supportive care.

Research into the molecular mechanisms of CNJ2 function and the development of therapeutic strategies for cone-rod dystrophy are active areas of study. Understanding the role of CNJ2 in cone photoreceptor development and function may lead to the identification of new targets for therapeutic intervention.
