centrosome duplication

The replication of a centrosome, a structure comprised of a pair of centrioles and peri-centriolar material from which a microtubule spindle apparatus is organized.

negative regulation of centrosome duplication

Any process that decreases the frequency, rate or extent of centrosome duplication. Centrosome duplication is the replication of a centrosome, a structure comprised of a pair of centrioles and peri-centriolar material from which a microtubule spindle apparatus is organized.

regulation of centrosome duplication

Any process that modulates the frequency, rate or extent of centrosome duplication. Centrosome duplication is the replication of a centrosome, a structure comprised of a pair of centrioles and peri-centriolar material from which a microtubule spindle apparatus is organized.

positive regulation of centrosome duplication

Any process that increases the frequency, rate or extent of centrosome duplication. Centrosome duplication is the replication of a centrosome, a structure comprised of a pair of centrioles and peri-centriolar material from which a microtubule spindle apparatus is organized.

pyrimidine dimer repair

The repair of UV-induced T-T, C-T and C-C dimers.

thymine/thymine mispair binding

Binding to a double-stranded DNA region containing a T/T mispair.

photoreactive repair

The repair of UV-induced T-T, C-T and C-C dimers by directly reversing the damage to restore the original pyrimidines.

aclacinomycin T methylesterase activity

Catalysis of the reaction: aclacinomycin T(1+) + H2O = 15-demethylaclacinomycin T + methanol + H+.

CD4-positive or CD8-positive, alpha-beta T cell lineage commitment

The process in which an immature T cell commits to CD4-positive T cell lineage or the CD8-positive lineage of alpha-beta T cells.

alpha-beta T cell differentiation

The process in which a precursor cell type acquires the specialized features of an alpha-beta T cell. An alpha-beta T cell is a T cell that expresses an alpha-beta T cell receptor complex.
