S6K2: The Neglected S6 Kinase Family Member
S6 kinase 2 (S6K2) is a member of the AGC kinases super-family. Its closest homolog, S6K1, has been extensively studied along the years. However, due to the belief in the community that the high degree of identity between these two isoforms would translate in essentially identical biological functions, S6K2 has been largely neglected. Nevertheless, recent research has clearly highlighted that t...
متن کاملCEP110 and ninein are located in a specific domain of the centrosome associated with centrosome maturation.
The mammalian centrosome consists of a pair of centrioles surrounded by pericentriolar material (PCM). The architecture and composition of the centrosome, especially the PCM, changes during the cell cycle. Recently, a subset of PCM proteins have been shown to be arranged in a tubular conformation with an open and a closed end within the centrosome. The presence of such a specific configuration ...
متن کاملCentrosome-associated NDR kinase regulates centrosome duplication.
Human NDR kinases are upregulated in some cancer types, yet their functions still remain undefined. Here, we report the first known function of a mammalian NDR kinase by demonstrating that human NDR directly contributes to centrosome duplication. A subpopulation of endogenous NDR localizes to centrosomes in a cell-cycle-dependent manner. Overexpression of NDR resulted in centrosome overduplicat...
متن کاملCloning and characterization of a cDNA encoding an A-kinase anchoring protein located in the centrosome, AKAP450.
A combination of protein kinase A type II (RII) overlay screening, database searches and PCR was used to identify a centrosomal A-kinase anchoring protein. A cDNA with an 11.7 kb open reading frame was characterized and found to correspond to 50 exons of genomic sequence on human chromosome 7q21-22. This cDNA clone encoded a 3908 amino acid protein of 453 kDa, that was designated AKAP450 (DDBJ/...
متن کاملCyclin-dependent kinase control of centrosome duplication.
Centrosomes nucleate microtubules and duplicate once per cell cycle. This duplication and subsequent segregation in mitosis results in maintenance of the one centrosome/cell ratio. Centrosome duplication occurs during the G1/S transition in somatic cells and must be coupled to the events of the nuclear cell cycle; failure to coordinate duplication and mitosis results in abnormal numbers of cent...
