Abstract
We discovered that recombinant antibody light chains having a murine secretory leader sequence and an SYE motif at the N-terminus are truncated during post-translational processing. This disclosure provides two protein engineering solutions: to alter the SYE amino acid sequence of the Lc N-terminus to other alternatives; or to change the secretory leader peptide sequence. We have shown that both of these solutions are effective for preventing N-terminal light chain truncation.
