Recombinant YHR052W-A is produced using E. coli expression systems. The protein is purified via affinity chromatography and supplied in a lyophilized Tris/PBS buffer with 6% trehalose (pH 8.0) . Storage recommendations include aliquoting to avoid repeated freeze-thaw cycles and maintaining temperatures at -20°C or -80°C .
While native YHR052W-A is considered non-functional, recombinant studies suggest limited roles:
Calcium Sensitivity Suppression: Overexpression suppresses Ca²⁺ sensitivity in mutants lacking inositol phosphorylceramide mannosyltransferases Csg1p and Csh1p .
Membrane Localization: Predicted to be a single-pass membrane protein, though this remains unverified experimentally .
Recombinant YHR052W-A is primarily used in:
Antibody Development: Rabbit polyclonal antibodies (e.g., MBS7151367) target this protein for ELISA and Western blot applications .
Protein Interaction Studies: STRING database annotations highlight weak associations with proteins like YHR054W-A (a dubious ORF) and HOR7 (a hyperosmotic stress-responsive protein) .
The YHR052W-A gene’s dubious status complicates its study. UniProt and SGD emphasize that comparative sequence data and experimental evidence do not support a functional role in S. cerevisiae . Recombinant versions may thus serve as negative controls or tools for probing gene annotation accuracy.
