Invitrogen™ Human NACA (aa 1995-2034) Control Fragment Recombinant Protein

Description

Highest antigen sequence indentity to the following orthologs: Mouse (100%), Rat (100%). This recombinant protein control fragment may be used for blocking experiments. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

NACA prevents inappropriate targeting of non-secretory polypeptides to the endoplasmic reticulum (ER). It binds to nascent polypeptide chains as they emerge from the ribosome and blocks their interaction with the signal recognition particle (SRP), which normally targets nascent secretory peptides to the ER. NACA also reduces the inherent affinity of ribosomes for protein translocation sites in the ER membrane (M sites), and may act as a specific coactivator for JUN, binding to DNA and stabilizing the interaction of JUN homodimers with target gene promoters.
