Proteoglycan linkage region glycosyltransferases B4GalT7, B3GalT6, B3GlcAT-1 are dimeric and show promiscuity towards complex type N-glycans. B3GalT6 is a covalent dimer linked by a disulfide in the center of the large dimerization domain. tinyurl.com/vb2auutu

Mutation c.548A>G (p.Asp183Gly) in the gene encoding A-glycosyltransferase results in the A(weak) trait by reducing the number of hydrogen bonds, which leads to decreased protein stability.

Interesting report shows that peptidylarginine deiminase 4 (PAD4), an enzyme responsible for citrullination of arginine in rheumatoid arthritis, is activated by glycosaminoglycans released from cartilage, which may exacerbate the symptoms.

Important issue!
Big day for foundational glycoRNA research, with two preprints published in Nature EMM. Both urge greater analytical rigour in the field.
1. RNA-associated glycoconjugates highlight potential
ambiguities in glycoRNA analysis
2. Proteins are a source of glycans found in preparations of glycoRNA

"World's first potential trillionaire has killed 600,000 people, including 400,000 children" is the only headline that anyone should ever read about Elon Musk
One analytical model shows that, as of November 5th, the dismantling of U.S.A.I.D. has already caused the deaths of 600,000 people, two-thirds of them children. https://newyorkermag.visitlink.me/jUzNSc

What happens if your asexual reproduction goes wrong? For instance, you can grow a head instead of a tail. But if you're a flatworm, it's not that bad - as we showed in our newest paper published in the Proceedings of the Royal Society B: tinyurl.com/4dnp2ffz
