Function

Substrate-recognition component of a Cul2-RING (CRL2) E3 ubiquitin-protein ligase complex of the DesCEND (destruction via C-end degrons) pathway, which recognizes a C-degron located at the extreme C terminus of target proteins, leading to their ubiquitination and degradation. The C-degron recognized by the DesCEND pathway is usually a motif of less than ten residues and can be present in full-length proteins, truncated proteins or proteolytically cleaved forms. The CRL2(KLHDC3) complex specifically recognizes proteins with a glycine (Gly) at the C-terminus, leading to their ubiquitination and degradation: recognizes the C-terminal -Arg-(Xaa)n-Arg-Gly, -Arg-(Xaa)n-Lys-Gly, and -Arg-(Xaa)n-Gln-Gly degrons.

The C-degron recognized by the DesCEND pathway is usually a motif of less than ten residues and can be present in full-length proteins, truncated proteins or proteolytically cleaved forms (PubMed:29775578, PubMed:29779948).

The CRL2(KLHDC3) complex mediates ubiquitination and degradation of truncated SELENOV and SEPHS2 selenoproteins produced by failed UGA/Sec decoding, which end with a glycine (PubMed:26138980). May be involved in meiotic recombination process (PubMed:12606021)

Subcellular Location

Cytoplasm

Subunit

Component of a CRL2(KLHDC3) complex, also named ECS(KLHDC3) complex, composed of CUL2, Elongin BC (ELOB and ELOC), RBX1 and substrate-specific adapter KLHDC3 (PubMed:29775578, PubMed:29779948). May form oligomers as a KLHDC3-ELOB-ELOC complex; this interaction is likely autoinhibitory for the E3 ligase complex (PubMed:36805027)
