E3 ubiquitin-protein ligase MYCBP2 (MYCBP2)

Atypical E3 ubiquitin-protein ligase which specifically mediates ubiquitination of threonine and serine residues on target proteins, instead of ubiquitinating lysine residues (PubMed:29643511). Reveals esterification activity towards both threonine and serine, with a preference for threonine, and acts through two essential catalytic cysteine residues that relay ubiquitin to its substrate via thioester intermediates (PubMed:29643511).

Involved in different processes like regulation of neurite outgrowth, synaptic development, synaptogenesis and axon degeneration (By similarity). Required for the formation of major central nervous system axon tracts (By similarity).
