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.

Features

Showing features for domain.

TypeIDPosition(s)Description
Domain1-86Signal recognition particle SRP54 helical bundle
Domain99-300AAA+ ATPase
Domain100-295SRP54-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.
