The recombinant Candida glabrata Signal Recognition Particle (SRP) SEC65 subunit (SEC65) is a genetically engineered protein derived from the CAGL0J06578g gene. It serves as a critical component of the SRP complex, which mediates co-translational targeting of secretory and membrane proteins to the endoplasmic reticulum (ER) in eukaryotes . SEC65 homologs are conserved across fungi, including Saccharomyces cerevisiae and Candida albicans, sharing structural and functional similarities with mammalian SRP19 .
Gene Locus: CAGL0J06578g is located on chromosome J in C. glabrata.
Orthologs:
The SRP complex in C. glabrata likely mirrors the S. cerevisiae SRP structure, which includes:
SRP54: Signal sequence-binding subunit.
scR1 RNA: Structural scaffold.
