PFDN2 Protein, Human (His)

The PFDN2 protein selectively binds to the cytoplasmic chaperone protein (c-CPN) and directs the protein for targeted transfer. It also interacts with nascent peptides and actively promotes correct folding in complex cellular environments. PFDN2 Protein, Human (His) is the recombinant human-derived PFDN2 protein, expressed by E. coli , with N-6*His labeled tag.

PFDN2 protein exhibits specific binding affinity to cytosolic chaperonin (c-CPN), facilitating the targeted transfer of proteins to this chaperone. Furthermore, PFDN2 interacts with nascent polypeptide chains, actively promoting their proper folding within an intricate cellular environment with numerous competing pathways for nonnative proteins. As a heterohexamer, PFDN2 comprises two PFD-alpha type and four PFD-beta type subunits. It plays a crucial role as part of the PAQosome complex, collaborating with other essential components such as R2TP complex members (RUVBL1, RUVBL2, RPAP3, and PIH1D1) and URI complex members (PFDN6, PDRG1, UXT, and URI1), as well as ASDURF, POLR2E, and DNAAF10/WDR92. This complex is integral to the biogenesis of various protein complexes. Notably, PFDN2 engages in phosphorylation-dependent interactions with URI1, demonstrating a growth-dependent manner of interaction.
