Cell adhesion molecule L1 regulates cellular responses in the developing and adult nervous system. L1 stimulation triggers sumoylation and cleavage of L1, thus generating the L1-70 fragment (1) which is cleaved by cathepsin E (2) yielding the L1-30 fragment that is imported to the nucleus (3), may bind to DNA and/or nuclear proteins (4), to regulate diverse cellular functions.
