ASB6 interacts with p62 and it is part of CRL5 E3 ligase complex. (A,B) HEK293T cells transfected with the indicated plasmids were treated with 10 μM MG132 for 10 h before harvest for Co-IP and IB analysis. (C) Schematic illustration of human ASB6 protein domain composition. (D,E) HEK293T cells were co-transfected with ASB6 wild type and mutants (Δ-SOCS box, Δ-Cul5-box) and HA-CUL5 (D) or HA-p62 (E) constructs. Cells were treated with 10 μM MG132 for 10 h before harvest for Co-IP and IB analysis. (F) Huh1 cells were treated with 10 μM MG132 for 10 h before harvest to make whole-cell lysates. ASB6 antibody was used to perform endogenous Co-IP experiments with Rabbit IgG as negative control.
