Complexes of D-type cyclins with CDKs during maize germination
The importance of cell proliferation in plant growth and development has been well documented. The majority of studies on basic cell cycle mechanisms in plants have been at the level of gene expression and much less knowledge has accumulated in terms of protein interactions and activation. Two key proteins, cyclins and cyclin-dependent kinases (CDKs) are fundamental for cell cycle regulation an...
متن کاملArabidopsis PCNAs form complexes with selected D-type cyclins
Proliferating Cell Nuclear Antigen (PCNA) is a key nuclear protein of eukaryotic cells. It has been shown to form complexes with cyclin dependent kinases, cyclin dependent kinase inhibitors and the D-type cyclins which are involved in the cell cycle control. In Arabidopsis two genes coding for PCNA1 and PCNA2 proteins have been identified. In this study by analyzing Arabidopsis PCNA/CycD comple...
متن کاملInvolvement of cdks and cyclins in muscle differentiation.
Myocyte differentiation is due to transcription of genes that characterize the phenotypic and biochemical identity of differentiated muscle cells. These are the myogenic regulatory factors (MRFs) MyoD, Myf5, myogenin and MRF4. Overexpression of cdk/cyclins has been reported to inhibit the activity of MyoD and prevent myogenic differentiation by different modalities. Unlike other cdk/cyclin comp...
متن کاملCdks, cyclins and CKIs: roles beyond cell cycle regulation.
Cyclin-dependent kinases (Cdks) are serine/threonine kinases and their catalytic activities are modulated by interactions with cyclins and Cdk inhibitors (CKIs). Close cooperation between this trio is necessary for ensuring orderly progression through the cell cycle. In addition to their well-established function in cell cycle control, it is becoming increasingly apparent that mammalian Cdks, c...
متن کاملMitochondrial biogenesis during germination in maize embryos.
Mitochondrial biogenesis and metabolism were investigated during maize (Zea mays) seed germination. Mitochondria from dry and imbibed seed exhibited NADH-dependent O(2) uptake that was completely inhibited by KCN and antimycin A. Mitochondria in the dry seed had a lower rate of succinate-dependent O(2) uptake relative to that measured in imbibed and germinated seed. The activities of the tricar...
