A basal body is a protein structure found at the base of a eukaryotic undulipodium. The basal body was named by Theodor Wilhelm Engelmann in 1880. It is formed from a centriole and several additional protein structures, and is, essentially, a modified centriole. The basal body serves as a nucleation site for the growth of the axoneme microtubules. Centrioles, from which basal bodies are derived, act as anchoring sites for proteins that in turn anchor microtubules, and are known as the microtubule organizing center (MTOC). These microtubules provide structure and facilitate movement of vesicles and organelles within many eukaryotic cells.
Robert G. Roeder is an American biochemist. He is known as a pioneer scientist in eukaryotic transcription. He discovered three distinct nuclear RNA polymerases in 1969 and characterized many proteins involved in the regulation of transcription, including basic transcription factors and the first mammalian gene-specific activator over five decades of research. He is the recipient of the Gairdner Foundation International Award in 2000, the Albert Lasker Award for Basic Medical Research in 2003, and the Kyoto Prize in 2021. He currently serves as Arnold and Mabel Beckman Professor and Head of the Laboratory of Biochemical and Molecular Biology at The Rockefeller University.
Transcription factor II D (TFIID) is one of several general transcription factors that make up the RNA polymerase II preinitiation complex. RNA polymerase II holoenzyme is a form of eukaryotic RNA polymerase II that is recruited to the promoters of protein-coding genes in living cells. It consists of RNA polymerase II, a subset of general transcription factors, and regulatory proteins known as SRB proteins. Before the start of transcription, the transcription Factor II D (TFIID) complex binds to the core promoter DNA of the gene through specific recognition of promoter sequence motifs, including the TATA box, Initiator, Downstream Promoter, Motif Ten, or Downstream Regulatory elements.
Cyclin E is a member of the cyclin family.
Nucleophosmin (NPM), also known as nucleolar phosphoprotein B23 or numatrin, is a protein that in humans is encoded by the NPM1 gene.
Serine/threonine-protein kinase PLK1, also known as polo-like kinase 1 (PLK-1) or serine/threonine-protein kinase 13 (STPK13), is an enzyme that in humans is encoded by the PLK1 gene.
Transcription factor E2F3 is a protein that in humans is encoded by the E2F3 gene.
Mitochondrial transcription factor A, abbreviated as TFAM or mtTFA, is a protein that in humans is encoded by the TFAM gene.
Activating transcription factor 5, also known as ATF5, is a protein that, in humans, is encoded by the ATF5 gene.
Afadin- and alpha-actinin-binding protein is a protein that in humans is encoded by the SSX2IP gene. It has been shown that it functions together with WDR8 in centrosome maturation, ensuring proper spindle length and orientation. The SSX2IP-WDR8 complex additionally promotes ciliary vesicle docking during ciliogenesis.
Transcription factor AP-2 alpha, also known as TFAP2A, is a protein that in humans is encoded by the TFAP2A gene.
Centrosome-associated protein CEP250 is a protein that in humans is encoded by the CEP250 gene. This gene encodes a core centrosomal protein required for centriole-centriole cohesion during interphase of the cell cycle. The encoded protein dissociates from the centrosomes when parental centrioles separate at the beginning of mitosis. The protein associates with and is phosphorylated by NIMA-related kinase 2, which is also associated with the centrosome. Furthermore, CEP135 is also required for the centriolar localization of CEP250.
Ubiquitin carboxyl-terminal hydrolase 20 is an enzyme that in humans is encoded by the USP20 gene.
Centriolar coiled-coil protein of 110 kDa also known as centrosomal protein of 110 kDa or CP110 is a protein that in humans is encoded by the CCP110 gene. It is a cell cycle-dependent CDK substrate and regulates centrosome duplication. CP110 suppresses a cilia assembly program.
Robert Tjian is a Hong Kong-born American biochemist best known for his work on eukaryotic transcription.
