D1′—a New Member of D1 Protein Family in Cyanobacteria

, 2013
The D1 protein of Photosystem II (PSII), encoded by the psbA genes, is an indispensable component of oxygenic photosynthesis. Due to strongly oxidative chemistry of PSII water splitting, the D1 protein is prone to constant photodamage requiring its replacement, whereas most of the other PSII subunits remain ordinarily undamaged.

D1 protein degradation during photoinhibition of intact leaves a modification of the D1 protein precedes degradation [PDF]

FEBS Letters, 1991
Illumination of intact pumpkin leaves with high light led to severe photoinhibition of photosystem II with no net degradation of the D1 protein. Instead, however, a modified form of D1 protein with slightly slower electrophoretic mobility was induced with corresponding loss in the original form of the D1 protein. When the leaves were illuminated in the

D1-protein dynamics in photosystem II: the lingering enigma

Photosynthesis Research, 2008
The D1/D2 heterodimer core is the heart of the photosystem II reaction center. A characteristic feature of this heterodimer is the differentially rapid, light-dependent degradation of the D1 protein. The D1 protein is possibly the most researched photosynthetic polypeptide, with aspects of structure-function, gene, messenger and protein regulation ...

Protein kinase D1: a protein of emerging translational interest

Frontiers in Bioscience, 2007
Protein kinases are of particular interest in treatment of human diseases because of their enzymatic activity and susceptibility to successful therapeutic targeting. Protein kinase D1 (PKD1), cloned from humans and mouse by two different groups and reported simultaneously in 1990s, is emerging as a protein of translational value.

D1-D2 protein degradation in the chloroplast

European Journal of Biochemistry, 1999
The D1 and D2 proteins of the photosystem II (PSII) reaction center are stable in the dark, while rapid degradation occurs in the light. Thus far, a quantitative correlation between degradation and photon fluences has not been determined. In Spirodela oligorrhiza, D1‐D2 degradation increases with photon flux.

The D1 and D2 Core Proteins

2005
In 1977, Chua and Gillham (J Cell Biology 74: 441–452) reported for the first time the existence of two chloroplast-encoded proteins within the thylakoid membrane of the green alga Chlamydomonas reinhardtii, which they termed D-l and D-2. The D1 and D2 proteins are now recognized as the Photosystem II reaction center polypeptides with a key role in ...

Cyclin D1 and retinoblastoma protein expression in Kaposi's sarcoma

Journal of Cutaneous Pathology, 1997
Cyclins are implicated in the induction and control of the cell cycle. Cyclin D1 regulates G1‐phase progression by phosphorylation of the retinoblastoma protein (pRb). The Kaposi's sarcoma‐associated herpesvirus/human herpesvirus 8 (KSHV) contains and transcribes an open reading frame with sequence similarities to cellular D‐type cyclins.

Protein kinase D1 inhibition interferes with mitosis progression

Journal of Cellular Physiology, 2019
Abstract Protein kinase D1 (PKD1) plays a vital role in signal transduction, cell proliferation, membrane trafficking, and cancer; however, the majority of the studies up to date had centered primarily on PKD1 functions in interphase, very little is known about its role during cell division.

Site-specific mutations of the N-terminal threonines in the D1 protein affects photoautotrophic growth but not D1 protein stability in Synechocystis 6803

Plant Molecular Biology, 1998
The cyanobacterium Synechocystis 6803 was engineered to produce a D1 protein where one or more of the N-terminal threonines at positions 2, 3 and 4 were replaced by other amino acid residues. No phenotypic effects were found for the T2S or T2L mutations, whereas the T2V, T2L;T4V and T2V;T3V;T4V mutations resulted in reduced photoautotrophic growth rate

Regulation of D1-protein degradation during photoinhibition of photosystem II in vivo: Phosphorylation of the D1 protein in various plant groups

Planta, 1995
Photoinhibition of PSII and turnover of the D1 reaction-centre protein in vivo were studied in pumpkin leaves (Cucurbita pepo L.) acclimated to different growth irradiances and in low-light-grown moss, (Ceratodon purpureus) (Hedw.) Brid. The low-light-acclimated pumpkins were most susceptible to photoinhibition.
