Stable recombinant production of codon-scrambled lubricin and mucin in human cells.

ABSTRACT: Widespread therapeutic and commercial interest in recombinant mucin technology has emerged due to the unique ability of mucin glycoproteins to hydrate, protect, and lubricate biological surfaces. However, recombinant production of the large, highly repetitive domains that are characteristic of mucins remains a challenge in biomanufacturing likely due, at least in part, to the inherent instability of DNA repeats in the cellular genome. To overcome this challenge, we exploit codon redundancy to encode desired mucin polypeptides with minimal nucleotide repetition. The codon-scrambling strategy was applied to generate synonymous genes, or "synDNAs," for two mucins of commercial interest: lubricin and mucin 1. Stable, long-term recombinant production in suspension-adapted human 293-F cells was
