Technical Data

ADP-Ribosylation Factor Domain Protein 1 (ARD1, ARFD1, ARF domain protein 1, GTP-binding Protein ARD-1, Tripartite Motif Protein 23, TRIM23, E3 Ubiquitin-protein Ligase TRIM23, RING Finger Protein 46, RNF46)
Description:
The ARF tumor suppressor is a critical regulator of p53 stability. In addition to p53, ARF1 binds to other proteins such as MDM2 and ARF-BP1, a large protein containing HECT, UBA and WWE motifs. ARFBP1 directly binds and ubiquitinates p53; this activity is inhibited by ARF, indicating that ARF-BP1 is a critical mediator of the p53-dependent and p53-independent tumor suppressor functions of ARF. ARF-BP1 can also catalyze the polyubiquitination of Mcl-1, an anti-apoptotic Bcl-2 family member involved in DNA damage-induced apoptosis. Elimination of ARF-BP1 expression by RNA interference stabilized Mcl-1 protein, resulting in an attenuation of apoptosis induced by DNA-damage agents.
