PVRL3
The pvrl3 Gene: A Key Player in Immunity and Beyond
Description
The pvrl3 gene, also known as nectin-3, encodes a protein that plays a crucial role in various cellular processes, including cell-cell adhesion, immune regulation, and tissue development. It is located on chromosome 11q23.3 and consists of 11 exons.
The pvrl3 protein is a type of immunoglobulin-like cell adhesion molecule (IgCAM) that is expressed on the surface of epithelial cells and immune cells. It interacts with other IgCAMs, such as nectin-1 and nectin-2, to form cell-cell adhesions. These adhesions are essential for maintaining tissue integrity and facilitating cell communication.
Associated Diseases
Mutations in the pvrl3 gene have been linked to several inherited diseases, including:
- Congenital myasthenic syndrome (CMS): A rare neuromuscular disorder characterized by muscle weakness and fatigue.
- Hereditary sensory and autonomic neuropathy type 2 (HSAN2): A neurodegenerative disorder affecting the peripheral nervous system, leading to sensory loss, muscle weakness, and autonomic dysfunction.
- Carcinoma: Mutations in pvrl3 have also been implicated in the development of certain types of cancer, such as lung cancer and breast cancer.
Did you Know ?
In a study of over 1000 individuals diagnosed with CMS, mutations in the pvrl3 gene were found to be responsible for approximately 50% of cases. This highlights the significant role of this gene in the pathogenesis of this rare disorder.
