Primate-specific regulation of the human glycosphingolipid gatekeeper UGCG - Nature
Cryogenic electron microscopy structures of full-length human UGCG, the gatekeeper that dictates the scale and composition of glycosphingolipid diversity, are reported, showing that it uses a metal-independent catalytic mechanism driven by an arginine network.

8/8 Together, our results connect paralog-specific dosage variation in protein digestion with population differentiation, structural evolution and dietary adaptation—across human populations and diverse mammalian lineages.

7/8 This pattern extends beyond humans. Across eutherian mammals, independent PGA expansions were enriched in plant-dominant lineages, suggesting that increased pepsinogen dosage has repeatedly emerged in association with dietary ecology.

6/8 How is this remarkable copy-number diversity generated? The PGA locus is highly structurally dynamic: recurrent nonallelic homologous recombination (NAHR) continually generates new structural variation on which evolutionary forces can act.

Quanyu Chen @yeezus-chen.bsky.social · 21/08/2026
5/8 The East–West divergence is driven primarily by expansion of PGA34A. Recombinant enzyme assays further showed that PGA34A is the most proteolytically active paralog in vitro, linking paralog-specific dosage to digestive capacity.

4/8 Modern and ancient genomes reveal contrasting evolutionary regimes: a recent selective sweep in East Eurasia, but signatures of balancing selection in the West. Ancient genomes further show that PGA copy number increased in the East over the past ~9,000 years.

Quanyu Chen @yeezus-chen.bsky.social · 21/08/2026
3/8 Across Eurasia, PGA copy number shows a striking west-to-east increase. This geographic variation also tracks regional reliance on plant-derived protein, linking PGA dosage variation to differences in dietary ecology.

2/8 Using 1,348 haplotype-resolved assemblies from recent pangenome resources including APG, HPRC, and HGSVC, we reconstructed copy-number and structural variation at the PGA locus across global populations.

Diet has repeatedly shaped the human genome, yet adaptation of protein digestion remains poorly understood. In our new preprint, we investigate the evolutionary history of the human pepsinogen A (PGA) locus.

4/8 Population genetics revealed contrasting regimes: a recent selective sweep in East Eurasia, but signatures of balancing selection in the West. Ancient genomes showed the same asymmetry—PGA copy number rose in the East over ~9,000 years, but remained stable in the West.

Quanyu Chen @yeezus-chen.bsky.social · 21/08/2026
3/8 PGA is also unusually dynamic. Pangenome-based reconstruction and 26 trios revealed recurrent nonallelic homologous recombination (NAHR), including two de novo events, continually regenerating copy-number diversity.

Quanyu Chen @yeezus-chen.bsky.social · 21/08/2026
2/8 The variation is not random across the locus. Nearly all CNV is driven by expansion of PGA34A, while PGA34B and PGA5 remain largely fixed at the boundaries. Across 1,348 complete haplotypes, we resolved 36 structural haplotypes.
