Note: The complete
sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is
translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application,
please explicitly request the full and complete sequence of this protein before ordering.
Protein Length
Full length protein
Tag Info
N-terminal 10xHis-tagged
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Storage Condition
Store at -20°C, for extended storage, conserve at -20°C or -80°C.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Involved in peroxisome biosynthesis and integrity. Assembles membrane vesicles before the matrix proteins are translocated. As a docking factor for PEX19, is necessary for the import of peroxisomal membrane proteins in the peroxisomes.

Thus, PEX19 and PEX3 peroxisome biogenesis factors provide an alternative posttranslational route for membrane insertion of the reticulon homology domain-containing proteins, implying that endoplasmic reticulum membrane shaping and peroxisome biogenesis may be coordinated.PMID:29396426
that newly synthesized UBXD8 is post-translationally inserted into discrete ER subdomains by a mechanism requiring cytosolic PEX19 and membrane-integrated PEX3, proteins hitherto exclusively implicated in peroxisome biogenesisPMID:27295553
This insertion of PEX3 into the ER is physiologically relevant.PMID:26572236
PEX16 mediates the peroxisomal trafficking of two distinct peroxisomal membrane proteins, PEX3 and PMP34, via the endoplasmic reticulumPMID:25002403

Data suggest that Pex19p probably functions as a chaperone for membrane proteins and transports them to peroxisomes by anchoring to Pex3p using residues 12-73 and 40-131.PMID:16895967
either one or two tryptophan residues of Pex3p (Trp-104 and Trp-224) are directly involved in binding to Pex19p.PMID:18174172
