culA

Cullin-1

770 amino acids

Probable core component of cullin-based SCF-like E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. The E3 ubiquitin-protein ligase activity of the complex is dependent on the neddylation of the cullin subunit (By similarity). Required at several stages during development. CulA and fbxA regulate multicellular development by targeting regA for degradation via a pathway that requires erkB function, leading to an increase in cAMP and PKA activity.

Belongs to the cullin family.
