Ation of p53 in mud crabs remains unclear. To address this situation, HUWE1 and TRAF6 were silenced, then the ubiquitination of p53 was evaluated. As shown in Fig. 3A and B, the depletion of HUWE1 would cause the accumulation of p53 protein, and also the ubiquitination of p53 was also decreased (Fig. 3B). Furthermore, p53 was accumulated when TRAF6 was suppressed (Fig. 3C and D); similarly, the ubiquitination of p53 was lowered (Fig. 3D). In addition, the overexpression of HUWE1 and TRAF6 could promote the ubiquitination of p53 and lead to the reduction of p53 in the protein level in S2 (Drosophila Schneider two) cells (Fig. 3E and F).
