Function
Probable substrate recognition component of SCF (SKP1-CUL-F-box protein) E3 ubiquitin-protein ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (PubMed:17626846). Regulates synapse elimination in early development in the motor neuron HSNL (PubMed:17626846). Cell autonomous negative regulator of lin-12/Notch-mediated signaling, with respect to lin-12 activity in cell fate decisions and tumorigenesis (PubMed:9389650). May target the intracellular domains of lin-12/Notch proteins for ubiquitin-dependent degradation (PubMed:9389650). Involved in sex determination by promoting female development (PubMed:15306688, PubMed:18718460). Potential regulator of presenilin (PubMed:9861048). May have a role in egg laying (PubMed:8293978, PubMed:15306688). Regulates zyg-1 levels (possibly redundantly with lin-23) to control centrosome duplication during mitosis (PubMed:22623721). Negatively regulates lin-45 activity and protein stability, probably by targeting it for ubiquitination and proteasomal degradation (PubMed:23154983).
