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 ...

Processing of D1 Protein: A Mysterious Process Carried Out in Thylakoid Lumen. [PDF]
Int J Mol Sci, 2022 In oxygenic photosynthetic organisms, D1 protein, a core subunit of photosystem II (PSII), displays a rapid turnover in the light, in which D1 proteins are distinctively damaged and immediately removed from the PSII.

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 ...
