Model confidence (pLDDT)

The mean pLDDT of this model is 92.3 (very high overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.

What pLDDT means and how to read it

Function

Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3 ubiquitin ligase complex that mediates the ubiquitination of target proteins, such as NPTXR, WNK1, WNK3 and WNK4, leading most often to their proteasomal degradation (PubMed:23838290). The BCR(KLHL2) complex catalyzes ubiquitination and degradation of NPTXR (By similarity). Responsible for degradative ubiquitination of the WNK kinases WNK1, WNK3 and WNK4 (PubMed:23838290). Plays a role in the reorganization of the actin cytoskeleton (PubMed:10397770). Promotes growth of cell projections in oligodendrocyte precursors (PubMed:15715669)

Subunit structure

Component of the BCR(KLHL2) E3 ubiquitin ligase complex, at least composed of CUL3 and KLHL2 and RBX1 (PubMed:23838290). Binds actin (PubMed:10397770). Interacts with KLHL12 (PubMed:15383316). Interacts (via N-terminus) with FYN (via SH3 domain) (PubMed:15715669)

Subcellular location

Cytoplasm, cytoskeleton, Cell projection, ruffle, Cell projection, Cell projection, lamellipodium, Cytoplasm, cytosol
