Biochemical and Physiological Mechanisms
DNAJB11 is a member of the evolutionarily conserved DNAJ/HSP40 family of proteins, which regulate molecular chaperone activity by stimulating ATPase activity. DNAJB11 serves as a co-chaperone for HSPA5 and binds directly to both unfolded proteins which ar

Recombinant Human DNAJB11 Protein (rp189392) - SDS-PAGE 
2 μg/lane of Recombinant Human DNAJB11 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 39.8 kDa under reducing conditions and 38.4 & 39.8 kDa under non-reducing conditions. 
The formation of intramolecular disulfide bonds among Cys-169, Cys-171, Cys-193, and Cys-196 in DNAJB11 could explain the presence of closely migrating isomers (Uniprot ID: Q9UBS4).
