Marissa Annis

Biochemistry PhD candidate at Cornell University | she/her | Studying chloroplast proteostasis in the @vanwijklab | Expected graduation May 2025

[Claire Ravenburg @ClaireRavenburg]

So excited to share our opinion paper in @TrendsPlantSci! We highlight the 9 Uvr-motif proteins in arabidopsis and propose regulatory roles for them in chloroplast proteostasis based on homologous systems in bacteria. I had a lot of fun writing with @marissa_annis & @vanwijklab!

[Marissa Annis @marissa_annis]

My first opinion paper is out! I learned so much writing it with @ClaireRavenburg @vanwijklab. We look at how Clp chaperone Uvr motifs regulate proteolytic activity and substrate selection and propose candidate regulator proteins in chloroplasts.

Intra-chloroplast proteases: A holistic network view of chloroplast proteolysis https://t.co/9ybUmoACOY

Our recent attempt to summarize and provide a more holistic view on the role of proteolysis in plastid biogenesis and functions.

Our new story about novel chloroplast Clp substrates including one with a very short half-life (minutes) is posted. "Stromal DUF760-1 and DUF760-2 proteins are degraded by the chloroplast Clp protease system but have very different half-lives" https://t.co/mKHFJu2KQK
