Desert hedgehog (protein)
Desert hedgehog (DHH) is a protein that in humans is encoded by the DHH gene. This protein is a member of the hedgehog signaling pathway and plays a key role in the development of the reproductive system and the peripheral nervous system.
Function[edit | edit source]
DHH is a molecule that is part of the hedgehog signaling pathway, a system that is essential for proper embryonic development. This protein is particularly important in the development of the male reproductive system, where it is involved in the formation of the testes and the sperm production process. In the peripheral nervous system, DHH plays a role in the formation of Schwann cells, which are responsible for the myelination of nerve fibers.
Structure[edit | edit source]
The DHH protein is a steroid-like molecule that is secreted by cells. It is composed of two parts: an N-terminal domain that is responsible for signaling activity, and a C-terminal domain that is involved in the processing and secretion of the protein. The N-terminal domain is highly conserved across species, indicating its importance in the function of the protein.
Clinical significance[edit | edit source]
Mutations in the DHH gene can lead to a variety of medical conditions. For example, mutations can cause gonadal dysgenesis, a condition in which the reproductive system does not develop properly. This can lead to infertility and a variety of other reproductive issues. Mutations can also cause neuropathy, a condition that affects the peripheral nervous system and can lead to symptoms such as pain, numbness, and weakness.
