Protein attributes

Sequence length	606 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Required for pseudopod elongation in transformed cells. Substrate-specific adapter of an E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Ref.6
Pathway	Protein modification; protein ubiquitination.
Subunit structure	Interacts with NRAP By similarity. Part of a complex that contains CUL3, RBX1 and KBTBD10.
Subcellular location	Cytoplasm. Cytoplasm › cytoskeleton. Cell projection › pseudopodium. Cell projection › ruffle. Note: Predominantly cytoplasmic but can co-localize with F-actin at the membrane ruffle-like structures at the tips of transformation-specific pseudopodia.
Tissue specificity	Sarcomeric muscle.
Post-translational modification	Ubiquitinated and probably targeted for proteasome-independent degradation. Ref.6
Sequence similarities	Contains 1 BTB (POZ) domain. Contains 5 Kelch repeats.
