Application

Heclin has been used as a HECT-type ubiquitin E3 ligase inhibitor in human embryonic kidney (HEK293) cells. It has also been used to test its effect on dandelion-induced chloride channel protein (ClC-Ka) inhibition in HEK293 cells and fibroblast-like COS-7 cell line.

Biochem/physiol Actions

Heclin is a selective reversible inihbitor of HECT E3 ubiquitin ligases. Heclin inhibited Nedd4, Smurf2 and WWP1 with IC50 values of 6.3 μM, 6.8 μM and 6.9 μM, respectively, and inhibited autoubiquitination of the Smurf2 HECT domain in vivo with an IC50 value of 9 μM. Heclin had no effect on the auto-ubiquitination of the RING domain ligase Mdm2.
Heclin is not effective in inhibiting E1 or E2 proteins.

The human genome encodes several hundred E3 ubiquitin ligases containing RING domains, and around 28 containing HECT domains. These enzymes catalyze the transfer of ubiquitin from E2 enzyme thioesters to a huge range of substrates and play crucial roles in

Ubiquitination is involved in synaptic plasticity and memory, but the involvement of HECT E3 ligases in these processes has not yet been established. Here, we bilaterally infused heclin, a specific inhibitor of some of these ligases, into the dorsal hippocampus
