About SRPDB

SRPDB assists the study of the structures and functions of signal recognition particles (SRPs). SRPDB provides annotated SRP RNA and SRP protein sequences, phylogenetically ordered and aligned. Included are representative RNA secondary structure diagrams where each base pair is proven by comparative sequence analysis, information about other proteins that play a role in SRP-mediated protein transloaction, as well as structural information about components of SRP.

Recent developments: A total of 1109 SRP RNA sequences grouped as Short bacterial (537), Long bacterial (96), Archaeal (81), Protozoan (82), Fungal/Metazoan-group (80), Plant (114), and Animal (119) SRP RNAs. See Rosenblad, M.A., Larsen, N., Samuelsson, T., and Zwieb, C. (2009) Kinship in the SRP RNA family. RNA Biol. 6, 508-516. [Abstract]
