SRP1 [YNL189W]
Serine-rich RNA polymerase I suppressor protein; Karyopherin alpha homolog; forms a dimer with karyopherin beta Kap95p to mediate import of nuclear proteins, binds the nuclear localization signal of the substrate during import; involved in cotranslational protein degradation; binds ribosome-bound nascent polypeptides; Srp1p and Sts1p couple proteasomes to nascent polypeptides emerging from the ribosome for cotranslational degradation
Synonyms: SRP1, SRP1p, Q02821, KAP60, N1606 ...
