protein involved in hair follicle development and regeneration
RSPO4 stands for R-spondin 4, a protein that plays a crucial role in the Wnt signaling pathway, which is important for cell growth and development. In the context of hair biology, RSPO4 is involved in the regulation of hair follicle development and regeneration. Mutations in the RSPO4 gene can lead to conditions like anonychia, where individuals are born without fingernails or toenails.
