pfam05486: SRP9-21 (this model, PSSM-Id:398894 is obsolete and has been replaced by 428490)
Signal recognition particle 9 kDa protein (SRP9)
This family consists of several eukaryotic SRP9 proteins. SRP9 together with the Alu-homologous region of 7SL RNA and SRP14 comprise the "Alu domain" of SRP, which mediates pausing of synthesis of ribosome associated nascent polypeptides that have been engaged by the targeting domain of SRP. This family also contains the homologous fungal SRP21.
