Descriptor properdina
Entry term(s) factor P del complemento
Scope note: Proteína de 53 kDa que es regulador positivo de la vía alternativa de la activación del complemento (VÍA ALTERNATIVA DE ACTIVACIÓN DEL COMPLEMENTO). Estabiliza la C3 CONVERTASA DE LA VÍA ALTERNATIVA (C3bBb) y la protege frente a una rápida inactivación, facilitando así la cascada de la ACTIVACIÓN DEL COMPLEMENTO y la formación del COMPLEJO DE ATAQUE A LA MEMBRANA. Los individuos con mutación en el gen PFC exhibe deficiencia de properdina y tienen una elevada susceptibilidad a las infecciones.

Scope note: A 53-kDa protein that is a positive regulator of the alternate pathway of complement activation (COMPLEMENT ACTIVATION PATHWAY, ALTERNATIVE). It stabilizes the ALTERNATIVE PATHWAY C3 CONVERTASE (C3bBb) and protects it from rapid inactivation, thus facilitating the cascade of COMPLEMENT ACTIVATION and the formation of MEMBRANE ATTACK COMPLEX. Individuals with mutation in the PFC gene exhibit properdin deficiency and have a high susceptibility to infections.
