Web4 jan. 2000 · Although rRNA nuclear export, which occurs as part of assembled ribosomal subunits, has not been extensively characterized, both tRNA export and U snRNA export are believed to depend on distinct members of the importin β family of nucleocytoplasmic factors, i.e., exportin t in the case of tRNA and Crm1 in the case of U snRNAs ( 5 ). WebThe signal peptide that sends a protein into the endoplasmic reticulum during translation is a series of hydrophobic (“water-fearing”) amino acids, usually found near the beginning (N-terminus) of the protein. When this sequence sticks out of the ribosome, it’s recognized by a protein complex called the signal-recognition particle (SRP ...
