The zeaxanthin epoxidase is degraded along with the D1 protein during photoinhibition of photosystem II [PDF]
Plant Direct, 2019 The xanthophyll zeaxanthin is synthesized in chloroplasts upon high light exposure of plants and serves central photoprotective functions. The reconversion of zeaxanthin to violaxanthin is catalyzed by the zeaxanthin epoxidase (ZEP).

Prognostic significance of cyclin D1 protein expression and gene amplification in invasive breast carcinoma. [PDF]
PLoS ONE, 2017 The oncogenic capacity of cyclin D1 has long been established in breast cancer. CCND1 amplification has been identified in a subset of patients with poor prognosis, but there are conflicting data regarding the predictive value of cyclin D1 protein ...

p53, p21, and cyclin d1 protein expression patterns in patients with breast cancer [PDF]
Veterinary World, 2021 Background and Aim: The mutation in the wild-type tumor suppressor gene p53 is the most common genetic change in human tumors. In addition, the normal function of p21, which is both antiproliferative and an inhibitor of the cell cycle, is disrupted in ...

Photosystem-II D1 protein mutants of Chlamydomonas reinhardtii in relation to metabolic rewiring and remodelling of H-bond network at QB site [PDF]
Scientific Reports, 2018 Photosystem II (PSII) reaction centre D1 protein of oxygenic phototrophs is pivotal for sustaining photosynthesis. Also, it is targeted by herbicides and herbicide-resistant weeds harbour single amino acid substitutions in D1.

PSB33 sustains photosystem II D1 protein under fluctuating light conditions. [PDF]
J Exp Bot, 2017 On Earth, solar irradiance varies as the sun rises and sets over the horizon, and sunlight is thus in constant fluctuation, following a slow dark-low-high-low-dark curve. Optimal plant growth and development are dependent on the capacity of plants to acclimate and regulate photosynthesis in response to these changes of light.

Response of the diatom Phaeodactylum tricornutum to photooxidative stress resulting from high light exposure. [PDF]
PLoS ONE, 2012 The response of microalgae to photooxidative stress resulting from high light exposure is a well-studied phenomenon. However, direct analyses of photosystem II (PSII) D1 protein (the main target of photoinhibition) in diatoms are scarce.

Hsc70 Regulates Accumulation of Cyclin D1 and Cyclin D1-Dependent Protein Kinase [PDF]
Molecular and Cellular Biology, 2003 The cyclin D-dependent kinase is a critical mediator of mitogen-dependent G1 phase progression in mammalian cells. Given the high incidence of cyclin D1 overexpression in human neoplasias, the nature and complexity of cyclin D complexes in vivo have been subjects of intense interest.
