ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Centromere assembly requires selective recognition of centromeric chromatin by centromere protein N
The kinetochore is a unique chromosomal locus that binds to the mitotic spindle so that chromosomes can segregate in mitosis. Kinetochore assembly requires the specialized chromatin of the centromere that is distinguished by the replacement of histone H3 with the histone H3‐variant centromere protein A (CENP‐A). CENP‐A is thought to epigenetically mark

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

PharmVar GeneFocus: NAT2—Genetic Variation and Updated Nomenclature
The Pharmacogene Variation Consortium (PharmVar) provides nomenclature for the highly polymorphic human N‐acetyltransferase 2 (NAT2) gene. NAT2 metabolizes several clinically used drugs including isoniazid, hydralazine, amifampridine, procainamide, and sulfonamides such as dapsone, and also some highly carcinogenic arylamines.

Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.
