The DNAJC3 Polyclonal Antibody (PAC046506) is a valuable tool for researchers studying DNAJC3, a protein involved in protein folding and quality control within the cell. This antibody, produced in rabbits, exhibits high reactivity towards human samples and is suitable for use in Western blot applications. By binding to the DNAJC3 protein, this antibody enables accurate detection and analysis in a variety of cell types, making it ideal for investigations in molecular biology and protein folding research.
DNAJC3, also known as the DnaJ homolog subfamily C member 3, is a crucial player in the cellular response to protein misfolding and stress. Its role in maintaining protein homeostasis makes it an intriguing target for studying neurodegenerative diseases, such as Alzheimer's and Parkinson's, as well as other protein misfolding disorders. Understanding the function of DNAJC3 is essential for developing therapeutic strategies aimed at restoring protein balance and preventing disease progression.

Background:
Involved in the unfolded protein response (UPR) during endoplasmic reticulum (ER) stress. Acts as a negative regulator of the EIF2AK4/GCN2 kinase activity by preventing the phosphorylation of eIF-2-α at 'Ser-52' and hence attenuating general protein synthesis under ER stress, hypothermic and amino acid, starving stress conditions (By similarity). Co-chaperone of HSPA8/HSC70, it stimulates its ATPase activity. May inhibit both the autophosphorylation of EIF2AK2/PKR and the ability of EIF2AK2 to catalyze phosphorylation of the EIF2A. May inhibit EIF2AK3/PERK activity.

NCBI Summary:
This gene encodes a protein with multiple tetratricopeptide repeat (TPR) motifs as well as the highly conserved J domain found in DNAJ chaperone family members. It is a member of the tetratricopeptide repeat family of proteins and acts as an inhibitor of the interferon-induced, dsRNA-activated protein kinase (PKR). [provided by RefSeq, Jul 2010]
