Signal-recognition-particle assembly has a crucial role in targeting secretory proteins to the rough endoplasmic reticulum membrane. It must be involved intimately in the translocation of a wide variety of protein substrates (By similarity). Fungal signal recognition particle consists of a 7S RNA molecule (scR1) and at least six protein subunits: SRP72, SRP68, SRP54, SEC65, SRP21 and SRP14. Belongs to the SRP19 family.
