Experimental data show that CDKs can be theoretically unified in the genes implicated in each case (40); proteins encoded by these genes are localized on renal epithelial cells and specifically on the primary cilium itself or the basal body and centrosome, with the only known exception being the gene product of MCKD2, Tamm-Horsfall protein (THP).
Further studies suggest that the cellular infrared detector resides at the cell center within the centrosome, and contains centrioles that are light sensors.
Centrosome protein centrin 2/caltractin 1 is part of the xeroderma pigmentosum group C complex that initiates global genome nucleotide excision repair.
Such ensembles are called a centrosomes (centriole+PCM) and becomes functional in the oocyte only after fertilization, when the sperm centrosome forms a sperm aster around duplicated centrioles--now called the zygote centrosome (7).
Upon the beginning of mitosis, they rapidly convert to a larger number of shorter and more dynamic microtubules surrounding each centrosome.
Katanin is a microtubule severing ATPase, known to localize at the centrosome in animal cells.
During embryo development the sperm centrosome forms the poles of the mitotic spindle, thereby regulating the first and subsequent cell divisions.
19) The authors of the study observed that primate reproductive biology is unique in that the proteins necessary for proper mitotic spindle pole formation and full embryological development reside along the unfertilized egg's meiotic spindle-chromosome complex and in the sperm's centrosome.
NPM1 acts as a molecular chaperone (1) and is thought to participate in preribosome maturation and centrosome duplication (2); in addition, it has been implicated in the regulation of the ArF-p53 tumor suppressor pathway (3,4).
Nuclear transfer involves transferring not just the nucleus of a cell, but also the centrosome and some cytoplasm.
Centrin 1 (Cetn1) is a retroposon-derived gene, located on chromosome 18A2, that encodes a protein component of the centrosome.
Centrosome localization is a dynamic, cell cycle, and cell type regulated process that plays many critical roles in a variety of cell functions and animal development.
