ab223607 Anti-Hsp40 antibody [3B9.E6] was shown to specifically react with Hsp40 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266344 (knockout cell lysate ab258400) was used. Wild-type and Hsp40 knockout samples were subjected to SDS-PAGE. ab223607 and Anti-beta Tubulin [EP1331Y] - Microtubule Marker (ab52901) were incubated overnight at 4°C at 1 in 500 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed (ab216777) and Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed (ab216772) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Biological function summary
Hsp40 proteins participate in cell signaling and stress response by modulating the activity of Hsp70 forming a functional complex with it to guide protein folding processes. This process is essential for protein quality control and cellular protection. It interacts with unfolded proteins and delivers them to Hsp70 enhancing its ATPase activity necessary for the proper functioning of these molecular chaperones. The expression of Hsp40 in stress conditions highlights its importance in the protein quality control system.
Pathways
Hsp40 is involved in important cellular mechanisms like the unfolded protein response and protein catabolism pathways. It works closely with Hsp70 playing a pivotal role in managing protein misfolding and aggregation vital for cellular stress response and recovery. In these pathways Hsp40's function ensures the proper folding and degradation of damaged proteins maintaining proteostasis in the cell.
