CC   -!- FUNCTION: Substrate-recognition component of a Cul2-RING (CRL2) E3
CC       ubiquitin-protein ligase complex of the DesCEND (destruction via C-end
CC       degrons) pathway, which recognizes a C-degron located at the extreme C
CC       terminus of target proteins, leading to their ubiquitination and
CC       degradation. The C-degron recognized by the DesCEND pathway is usually
CC       a motif of less than ten residues and can be present in full-length
CC       proteins, truncated proteins or proteolytically cleaved forms. The
CC       CRL2(FEM1B) complex specifically recognizes proteins ending with -Gly-
CC       Leu-Asp-Arg, leading to their ubiquitination and degradation.
CC       {ECO:0000250|UniProtKB:Q9UK73}.
CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC       {ECO:0000250|UniProtKB:Q9UK73}.
CC   -!- SUBUNIT: Component of a CRL2 E3 ubiquitin-protein ligase complex, also
CC       named ECS (Elongin BC-CUL2/5-SOCS-box protein) complex.
CC       {ECO:0000250|UniProtKB:Q9UK73}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9UK73}. Nucleus
CC       {ECO:0000250|UniProtKB:Q9UK73}.
CC   -!- SIMILARITY: Belongs to the fem-1 family. {ECO:0000305}.
