Summary

ASB9 (ankyrin repeat and SOCS box containing 9, HGNC:17184) is a protein-coding gene on chromosome Xp22.2, encoding Ankyrin repeat and SOCS box protein 9 (Q96DX5). Substrate-recognition component of a cullin-5-RING E3 ubiquitin-protein ligase complex (ECS complex, also named CRL5 complex), which mediates the ubiquitination and subsequent proteasomal degradation of target proteins.

This gene encodes a member of the ankyrin repeat and suppressor of cytokine signaling (SOCS) box protein family. Members of this family can interact with the elongin B-C adapter complex via their SOCS box domain and further complex with the cullin and ring box proteins to form E3 ubiquitin ligase complexes. They may function to mediate the substrate-recognition of the E3 ubiquitin ligases. A transcribed pseudogene of this gene has been identified on chromosome 15. Multiple transcript variants encoding different isoforms have been found for this gene.

UniProt curated annotations — full annotation on UniProt →

Function. Substrate-recognition component of a cullin-5-RING E3 ubiquitin-protein ligase complex (ECS complex, also named CRL5 complex), which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. The ECS(ASB9) complex catalyzes ubiquitination of creatine kinases CKB and CKMT1A. Does not interact with the Elongin BC complex, likely to be a negative regulator of isoform 1.

Subunit / interactions. Substrate-recognition component of the ECS(ASB9) complex, composed of ASB9, CUL5, ELOB, ELOC and RNF7/RBX2.

Subcellular location. Mitochondrion.

Tissue specificity. Predominantly expressed in testis, kidney, and liver.

Pathway. Protein modification; protein ubiquitination.

Similarity. Belongs to the ankyrin SOCS box (ASB) family.
