Alternative Name(s) |
Nascent polypeptide-associated complex subunit beta ; NAC-betaRNA polymerase B transcription factor 3 |
Relevance |
When associated with NACA, prevents inappropriate targeting of non-secretory polypeptides to the endoplasmic reticulum (ER). Binds to nascent polypeptide chains as they erge from the ribosome and blocks their interaction with the signal recognition particle (SRP), which normally targets nascent secretory peptides to the ER. BTF3 is also a general transcription factor that can form a stable complex with RNA polymerase II. Required for the initiation of transcription. |

Purity |
Greater than 90% as determined by SDS-PAGE. |
Storage Buffer |
Tris-based buffer, 50% glycerol |
Storage |
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 -20C/-80C. The shelf life of lyophilized form is 12 months at -20C/-80C. |
Notes |
Repeated freezing and thawing is not recommended. Store working aliquots at 4C for up to one week. |
