Abstract excerpt
In mammalian cells the signal recognition particle (SRP) consists of a approximately 300 nucleotide RNA and six proteins. Although the molecular structure and functional cycle of the SRP are both very well understood, far less is known about how the SRP is first assembled in the cell. Recent work has suggested that SRP assembly begins in the nucleoli. When NRK (rat fibroblast) cells were treated with leptomycin B...
