• Analysis of ADRM1 interactions with proteins like Phg2, HDAC8, and PADI4.
• Investigation of ADRM1's role in various cancers and physiological processes.
• Identification and evaluation of small-molecule inhibitors targeting ADRM1.

Main Results:

• ADRM1 coordinates substrate recognition and deubiquitination within the 26S proteasome.
• Overexpression of ADRM1 is linked to proliferation, migration, metastasis, and therapeutic resistance in multiple cancers.
• ADRM1 influences bone metabolism, reproduction, and immune regulation.
• Small-molecule inhibitor RA190 selectively targets the ADRM1 Pru domain, demonstrating anti-tumor efficacy.

Conclusions:

• ADRM1 is a critical molecular hub connecting proteasomal activity with signaling pathways.
