UniProt functional annotation for Q58440

UniProt code: Q58440.

Organism: Methanocaldococcus jannaschii (strain ATCC 43067 / DSM 2661 / JAL-1 / JCM 10045 / NBRC 100440) (Methanococcus jannaschii).
Taxonomy: Archaea; Euryarchaeota; Methanomada group; Methanococci; Methanococcales; Methanocaldococcaceae; Methanocaldococcus.
 
Function: Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds directly to 7S RNA and mediates binding of the 54 kDa subunit of the SRP. {ECO:0000255|HAMAP- Rule:MF_00305}.
 
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. {ECO:0000255|HAMAP-Rule:MF_00305}.
Subcellular location: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00305}.
