. 2022 Aug;
236(4):1339-1357.
PMID: 35946374
A network of peptidases governs proteostasis in plant chloroplasts and mitochondria. This study reveals strong genetic and functional interactions in Arabidopsis between the chloroplast stromal CLP chaperone-protease system and the...

. 2022 Jan;
298(3):101609.
PMID: 35065075
The chloroplast chaperone CLPC1 unfolds and delivers substrates to the stromal CLPPRT protease complex for degradation. We previously used an in vivo trapping approach to identify interactors with CLPC1 in...

72(13):4663-4679.
PMID: 33884419
Plastoglobules are dynamic protein-lipid microcompartments in plastids enriched for isoprenoid-derived metabolites. Chloroplast plastoglobules support formation, remodeling, and controlled dismantling of thylakoids during developmental transitions and environmental responses. However, the specific...

Plant Physiol
. 2020 Jul;
184(1):110-129.
PMID: 32663165
Chloroplast proteostasis is governed by a network of peptidases. As a part of this network, we show that Arabidopsis () chloroplast glutamyl peptidase (CGEP) is a homo-oligomeric stromal Ser-type (S9D)...

Plant Cell
. 2018 Feb;
30(3):543-562.
PMID: 29453228
N-terminal myristoylation, a major eukaryotic protein lipid modification, is difficult to detect in vivo and challenging to predict in silico. We developed a proteomics strategy involving subfractionation of cellular membranes,...

Cancer Cell
. 2017 Mar;
31(3):436-451.
PMID: 28292441
Recurrent point mutations in SPOP define a distinct molecular subclass of prostate cancer. Here, we describe a mouse model showing that mutant SPOP drives prostate tumorigenesis in vivo. Conditional expression...

. 2015 Oct;
27(10):2677-91.
PMID: 26419670
Clp proteases are found in prokaryotes, mitochondria, and plastids where they play crucial roles in maintaining protein homeostasis (proteostasis). The plant plastid Clp machinery comprises a hetero-oligomeric ClpPRT proteolytic core,...

PMID: 25921872
Plastid ClpT1 and ClpT2 are plant-specific proteins that associate with the ClpPR protease. However, their physiological significance and structures are not understood. Arabidopsis thaliana loss-of-function single clpt1 and clpt2 mutants...

PMID: 25845484
Hemibiotrophic plant pathogens, such as the oomycete Phytophthora infestans, employ a biphasic infection strategy, initially behaving as biotrophs, where minimal symptoms are exhibited by the plant, and subsequently as necrotrophs,...
