CC -!- FUNCTION: Component of the signal recognition particle (SRP) complex, a
CC ribonucleoprotein complex that mediates the cotranslational targeting
CC of secretory and membrane proteins to the endoplasmic reticulum (ER).
CC {ECO:0000256|RuleBase:RU364034}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58189; EC=3.6.5.4;
CC Evidence={ECO:0000256|ARBA:ARBA00035589};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:19670;
CC Evidence={ECO:0000256|ARBA:ARBA00035589};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|RuleBase:RU364034}. Endoplasmic reticulum
CC {ECO:0000256|ARBA:ARBA00004240}.
CC -!- DOMAIN: The M domain binds the 7SL RNA in presence of SRP19 and binds
CC the signal sequence of presecretory proteins.
CC {ECO:0000256|RuleBase:RU364034}.
CC -!- DOMAIN: The NG domain, also named G domain, is a special guanosine
CC triphosphatase (GTPase) domain, which binds GTP and forms a guanosine
CC 5'-triphosphate (GTP)-dependent complex with a homologous NG domain in
CC the SRP receptor subunit SRPRA. The two NG domains undergo cooperative
CC rearrangements upon their assembly, which culminate in the reciprocal
CC activation of the GTPase activity of one another. SRP receptor
CC compaction upon binding with cargo-loaded SRP and GTPase rearrangement
CC drive SRP-mediated cotranslational protein translocation into the ER.
CC {ECO:0000256|RuleBase:RU364034}.
CC -!- SIMILARITY: Belongs to the GTP-binding SRP family. SRP54 subfamily.
CC {ECO:0000256|ARBA:ARBA00005450, ECO:0000256|RuleBase:RU364034}.
