Protein Structure
UniProt Annotation
Function Substrate-recognition component of the SCF (SKP1-CUL1-F- box protein)-type E3 ubiquitin ligase complex. Promotes the proteasome-dependent degradation of key sarcomeric proteins, such as alpha-actinin (ACTN2) and filamin-C (FLNC), essential for maintenance of normal contractile function. {ECO:0000269PubMed:22972877}.
Subcellular Localization Cytoplasm, myofibril, sarcomere, Z line {ECO:0000250}.
Disease Associations
Tissue Specificity Predominantly expressed in liver, also enriched in cardiac muscle. {ECO:0000269PubMed:22972877}.
