Background
Anaphase‑promoting complex subunit 11 (APC11) is a small RING‑H2‑finger protein that forms part of the anaphase‑promoting complex/cyclosome (APC/C), an E3 ubiquitin ligase essential for cell‑cycle progression from metaphase to anaphase through targeted degradation of key regulatory proteins by the 26S proteasome. APC11 contains a canonical RING‑H2 domain comprising non‑tandem histidine and cysteine residues that coordinate zinc ions and confer structural similarity to the RING domains of RBX1 and RBX2 in SCF‑type E3 ligases. Within the APC/C, APC11 heterodimerizes with the cullin‑like subunit APC2 to form the catalytic core, and this APC2–APC11 module functions as a ubiquitin‑acceptor scaffold that recruits ubiquitin‑charged E2 enzymes such as UBE2S and UBE2C, thereby enabling the assembly of polyubiquitin chains on APC/C substrates. The activity of the APC/C complex depends on coactivators CDC20 and Cdh1 (FZR1), which recognize substrate proteins via D‑box and KEN‑box motifs and present them to the APC2–APC11–APC10 ubiquitylation site, ensuring timely turnover of cyclins, securin, and other cell‑cycle regulators. Mutations that disrupt the integrity of the APC11 RING‑H2 finger abolish ubiquitin‑chain formation and compromise APC/C‑dependent substrate degradation. APC11 is required for the metaphase‑to‑anaphase transition, chromosome segregation, and exit from mitosis, and it is studied as a core catalytic component of the APC/C and as a mechanistic node in cell‑cycle control and genome‑stability pathways.
