Function

function

Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Interaction

Subunit

Part of the signal recognition particle protein translocation system, which is composed of SRP and FtsY. Archaeal SRP consists of a 7S RNA molecule of 300 nucleotides and two protein subunits: SRP54 and SRP19.

Family & Domains

Features

Showing features for domain.

TypeIDPosition(s)Description
Domain1-85Signal recognition particle SRP54 helical bundle
Domain98-297AAA+ ATPase
Domain99-292SRP54-type proteins GTP-binding

Domain

Composed of three domains: the N-terminal N domain, which is responsible for interactions with the ribosome, the central G domain, which binds GTP, and the C-terminal M domain, which binds the RNA and the signal sequence of the RNC.

Sequence similarities

Belongs to the GTP-binding SRP family. SRP54 subfamily.
