简介
The PFDN4 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. PFDN4 Protein, Human (His) is the recombinant human-derived PFDN4 protein, expressed by E. coli , with N-6*His labeled tag.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Protein Description
PFDN4 (Prefoldin 4) is a member of the prefoldin family, which plays a crucial role in protein biogenesis by assisting in the proper folding of nascent polypeptides. It is particularly important in the assembly of multi-subunit protein complexes and in cellular responses to stress. Recent studies have implicated PFDN4 in various physiological processes, including those associated with the regulation of cell proliferation and differentiation. Dysregulation or mutations in the PFDN4 gene have been linked to several diseases, including certain cancers and neurodegenerative disorders, making it a focal point of research for understanding these conditions. Moreover, PFDN4's interaction with several molecular chaperones positions it as a key player in maintaining cellular homeostasis and protein integrity under stress conditions. The recombinant expression of PFDN4 in various systems provides valuable insights into its functional mechanisms and interactions with other proteins, thereby enhancing our understanding of its biological roles and potential therapeutic applications. As the study of PFDN4 continues to evolve, it holds promise for elucidating novel pathways in protein misfolding diseases and could lead to the development of new strategies for intervention and treatment.
