PFDN4: Proteins and Enzymes

PFDN4, also known as Prefoldin subunit 4, is a 134 amino acid protein that is 15 kDa, binds specifically to cytosolic chaperonin (c-CPN) and transfers target proteins to it, promotes folding in an environment in which there are many competing pathways for nonnative proteins, and is one of six subunits of prefoldin, a molecular chaperone complex that binds and stabilizes newly synthesized polypeptides, thereby allowing them to fold correctly. Current research is being performed on this protein involvement in b-cell non-hodgkin lymphoma, non-hodgkin lymphoma, hodgkin's lymphoma, hereditary angioedema, myocardial infarction, sinusitis, gastric cancer, colorectal cancer, breast cancer, cerebritis, cholesterol, and malaria. The PFDN4 has also been shown to have interactions with MAP3K3, ACTB, PRPF4, TUBA3E, PFDN2, and plus 80 other proteins in chaperonin-mediated protein folding, prefoldin mediated transfer of substrate to CCT/TriC, cooperation of Prefoldin and TriC/CCT in actin and tubulin folding, metabolism of proteins, and protein folding pathways.
