Data Sheet: 

HECTD2 (aka "HECT domain-containing protein 2" or "HECT-type E3 ubiquitin transferase HECTD2") is a 776 amino acid member of the HECT (Homologous to E6AP Carboxyl Terminus) domain family of Ubiquitin ligases.  With a predicted weight of 88 kDa, human HECTD2 shares 89% identity and 94% similarity with the mouse orthologue.  In innate immunity HECTD2 exerts a pro-inflammatory effect by contributing to the ubiquitylation and degradation of PIAS1, a multifunctional and potent anti-inflammatory protein that negatively regulates several key inflammatory pathways.  Small molecule inhibitors of HECTD2 were found to attenuate lipopolysaccharide (LPS)-induced lung inflammation.  HECTD2 has also been shown to ubiquitylate BoNT/A, a catalytic light chain of botulinum neurotoxin.  Ubiquitylation can lead to the proteasomal degradation of the light chain, but it's rescued from destruction by the dominant effect of a deubiquitinating enzyme, VCIP135/VCPIP1.
